Code that isn’t at all poetry, but that is structure & patterns

Happy Poetry Month! Rather than poeting, for the past few days I’ve been twiddling with code. It is much the same state of mind as translating, or basic composition, but for me at least, not quite poetry. It does require moving a bunch of words around, arranging them, and imagining their interpretation, organizing words in order to have an effect. For poetry or composition, an effect on a listener/reader, so you are imagining a logical and emotional state and the interpretation and effect of a person. For code obviously you are writing so that a machine will follow your orders perfectly; but less obviously you are writing for yourself in the future and for other future, human readers of your procedural pattern of thought. You are writing for your future (self or other) human, so they can modify and extend that code and put it to other uses. In other words, it has a bit in common with an oral or folk tradition. Repetition and patterns are good in poetry if you want to create structure for extension and improvisation.

So, just now I was doing some of my baby-Perl for some contract work. And the deal is, there are a bunch of users, and their accounts go through various bureaucratic steps, and through various work people and departments, some steps requiring others to happen first, for the account to become fully active. This is a fairly common situation for any institution. So, I had a Perl script that would take some command line options and then would do various things with the user and account data. As more people started realizing I could manipulate account stuff, and could generate reports, etc, they started asking me for new tasks. So, the hacky little script grew very quickly to a giant horrible tangly mess full of regular expressions that I did not understand anymore, 30 minutes after I wrote and tested them. A reg exp is a thing of beauty but it is not a joy forever. Instead, it makes my head hurt.

So I started about 4 times over this last month to rewrite that mess to make it easily understandable and extensible. I scribbled and thought on post-it notes so I could try to break down what needed to happen into chunks that I could move around & visualize, easier than in a 200 line text file.

It went kind of like this: use GetOpt::Long to tell from the command line what kind of report or change is required. Log in to several systems. Iterate over a range of account IDs in a big loop. Then do some http page getting and parsing. Then a lot of if else statements to see what command line option is turned on. Mixed in with some more tests and if elsing. Then again depending on command line option, do some other junk, write to some other web pages and outfiles. At the end of all that looping, write some more outfiles.

Ugh! You can see that any new capability meant that I had to do more page parsing and more reg exping, as well as thinking through all the logic of the whole if-else mess.

Today I suddenly realized several things. Speed doesn’t matter for this. I can set it going and let it chug away.

So, number one, for each user ID, just read in all the possible pages that have info on that account. It is only 5 web pages on 3 different systems. Read them in and parse out all their fields.

Number two, think of each account as having a state. There are 8 different bits of information that change account state, out of the 50+ possible bits of info. So, after parsing all the pages, look at the 8 pieces of information I care about, to determine the account’s state.

For things I then want to do, they fall into two categories. Reporting and state change. Reporting is easy. For changing account state, I can define for each case of one state to another; what actions it takes to change the account state. There are objects, and states, and transactions.

I have never really understood object-orientedness no matter how many times I think about it, and use and write code that is in theory, sort of object-oriented. It’s not like I get it now, but I get it more than I did.

Suddenly everything clicked into place and I understood how to write the code in a way that would be useful and elegant. I understood the root of the problem. It all fell together in a system. It looked like a pattern, like information that was beautiful. I know, it is a bunch of account data in a bureaucratic procedure. After years of being “programmer analyst” doing back end tools for university departments, I had to find beauty where I could. The “click” feeling means I look back on my month of sporadic attempts to write this program, and it looks like I was brain-deadishly trying to make something out of legos by gluing their corners together, when all the while I could have been snapping them together how they are supposed to go. But, before, I could not see the intersections.

So, just now I had the exhilarating (yet slightly shame-faced) feeling that I had just reinvented the wheel, or some basic principle of computer science that if I had any sense, I would have known from taking some classes. On the other hand, taking computer science classes doesn’t guarantee you know what you are doing or can build something that other people find useful & usable.

Highly trained girl-monkey sys admin bait

geeking at the conference
Originally uploaded by Liz Henry

I was saddened and angered recently at a geeky gathering, to hear a very annoying and sexist story about women at techology conferences. A young man was talking to another guy and a couple of women who also looked to be in their 20s. He was laughing and telling a story with a tone of “Wow, listen to this hilarious amazing thing!”

According to this poor little dude, it is hilarious that it has become common that at sys admin and other tech conferences, big companies send women in undercover to do stealth recruiting. His story laid out how the big companies “specially train the women to sound like they know what they’re talking about”, priming them with lessons in the correct use of technical jargon. They send sexy women who are basically “high class call girls” to flirt with the valuable (assumed unquestioningly to be male) sys admins and programmers and get their information, and to figure out which ones are good and know their job. Then the Trained Monkey Fake Sys Admin Whores pass that information on to their superiors (also assumed in the story to be male) who actually know what computers are, for them to do intensive recruiting.

“Hahahaha!” laughed the young women at the party.

“Wow, hahahah!” laughed the guy listening.

“It’s totally true!” said the young spreader of poisonous, sexist, urban myths. “I even know guys who have slept with them!”

Oh for fuck’s sake. Let’s just undermine the legitimacy of technical women at conferences just A LITTLE BIT MORE with our messed-up “booth babe” stories, shall we?

If this even had a grain of truth to it, what would it sound like, framed differently? “Some companies send technical recruiters to technical conferences.” That’s it. There is nothing newsworthy there. I mean, DUH.

But, as soon as there are WOMEN in the story, it is given a misogynist spin, which is assumed to be hilarious and titillating and to make the listener feel superior. Because the technical recruiters are female, they are sluts, or “call girls”; definitely sexually available and exploitable. Because they are female, they are assumed in the story to be ignorant of computers, technology, sys adminning, and programming; any knowledge they DO have is “fake” because it is is artificial “training” given to them as a thin veneer just to mask their real goal which is sexual predation on the sys admins, run by mythical “big company” pimps.

I was super amazed to hear this crap coming out of someone’s mouth, at a party which was chock full of skilled, amazing, geeky women, and men who are sweet feminist allies. But, on the other hand, I was not amazed, because this is exactly the sort of thing people say all the time about, and around, technical women, or any women in male-dominated fields. It is part of the background of undermining and de-legitimizing women, that poisons the fucking air we breathe, that makes people assume we suck, that makes us women have to prove ourselves in every new professional context, to everyone we meet, that means we have to be 10 times better than a man in a comparable context before other people believe in our professional credentials.

Just think about that next time you hear a bunch of dudes arguing about why there aren’t more women in programming and engineering, and, quit looking for your biological explanations, and go check your own assumptions, and the kind of stories you tell and tolerate in your communities.

Down with keyboards, down with pants!

I was thinking today about my silly invention of “smart pants” so that people could just type on their pants. Then I realized something crucial:

Who needs pants!

Seriously, to hell with pants! Down with pants!

Not to mention down with keyboards.

Instead maybe we’ll have little motion detecting rings on our fingers and will just make the barest hints of typing motions. The micro-intent to move will be sensed by the set of rings with tiny wireless transmitters. Or for the prototype, you could have the rings wire up like flexible brass knuckles to a bracelet with the transmitter.

So if I end up like this eventually, I won’t have to type 15 words a minute, and I hope also not to talk like a Dalek.

Why have typing motions at all, then? It might be important to have some kind of physical motion and body memory.

And as I contemplate this Ankle-Foot Orthosis that will soon be mine, I wonder why the thing, cool as it looks (yay for rehab equipment with style!) doesn’t have all kinds of electronic sensors in it. I don’t ask for it to move my foot around, or walk for me like a real exoskeleton would. But I WANT ITS DATA. Data, goddamn it! Think of all the cool data it could be collecting on my gait, on the strength of my hamstrings as my back toe is pushing off. Instead of whining that as the day goes on my leg gets weaker, I could just have a handy graph on my blog so that anyone who cared to know would see how well I’m walking. I noticed at BlogHer that there were exercise pedometer sorts of things that upload and track your workouts on a website and even on social sites. How about for rehab too?

I hope to see some of these mad inventions in the next few years.

Wear your fandom

Two things that got me thinking today:

A bracelet flash drive in pink and blue rubber. Like jelly bracelets but with 512 MB of space! If I were a teenager I would be wearing my chat program and archives here, and my private diaries, and maybe a little music. Making it a bracelet is a great idea – who doesn’t hate the usual drive design with the little caps that come off and get lost?

To this thought I will add the lovely illustration of Moore’s Law: 512 MB drives for 99 cents.

I realize I’m jaded now and expect to carry around a month’s worth of music with no repeats in an Altoids tin. Very soon we’ll have nice jewelry for our hard drives, and not just cheap jelly bracelets.

If I were a computer manufacturer or a media conglomerate I’d be doing stuff like putting Buffy DVD collections onto fancy Buffy themed bracelets. We aren’t quite to the point of carrying all human-generated information on a tiny holocube crystal earring. But the DVD bracelets will be great – have your stuff around handy to watch any time. There’s all sorts of stuff to put onto wearable computers, but probably videos will be the killer. Spiffing up the jewelry with visible identifiers or particular styles means you’ll be able to wear your fandom.

Keyboard shortcuts in Thunderbird, and the failures of visual metaphors

This is so great, I’m feeling all bouncy! There is a Thunderbird extension, Nostalgy, for using keyboard shortcuts to do everything. I was just feeling super pissy that this didn’t exist, and wishing someone would write it, because I hate mousing or trackpadding: it slows me down. If I’m just using typing shortcuts, then I can get the feel of the commands in my fingers, like playing piano or Nethack, and I don’t have to think about what to do. So, now I’m super happy that it *does* exist (thanks to Oblomovka for the link). You can get the latest version here and in fact there are instructions on how to update directly from svn for the latest bug fixes.

Meanwhile, I’m really enjoying yubnub and its keystroke commands. I don’t have to do any slow mousing that requires hand-eye coordination, or extra shoulder/wrist movements that flare up old RSI problems. Instead I am training my fingers to go “apple-K wp” if I want to search Wikipedia. It becomes automatic, and I don’t have to think about it. I can do it with my eyes closed, lightning fast.

I look forward to getting back into that mode for email! I like Thunderbird, but I miss Pine because of the speed and efficiency of keyboard shortcuts.

This was something we talked about during She’s Geeky, at Beth Kanter and Elizabeth Perry‘s session on non-profits. Someone mentioned that very small technological interventions can make huge changes in a whole organization.

I found this to be true at the businesses, schools, and universities where I did tech support and training. Training classes were useful, but the best way to help a person work with their computer was to watch them work for even a few minutes, and then teach them at least one way to improve their basic workflow. A few simple tricks made people more confident and productive and happy. Those tricks would then spread throughout an organization. Sometimes, this is as simple as teaching a person that in menus, the underlined letter or the keys next to the command are keyboard shortcuts that they can learn. Or, a small trick like using tabs in a web browser can help people enormously. Many people, especially baby boomers, don’t feel comfortable with basic navigation on a computer desktop, no matter what system they’re on. The concepts that go along with productivity tricks can also help people’s understanding of what they’re doing on a computer, so they feel less like they’re flailing and instead, have constructed a mental map or geography of what’s happening.

It is amazing, but most people who use computers every day at work and at home still don’t have basic concepts down. It is like they have their eyes shut, and are trying to walk around their house by counting the number of steps to go in each direction, and they’re never sure which direction they’re pointing until they hit a wall. But most computer classes are procedural. You end up with a step by step list of what to do to produce a result, but with no understanding of what just happened.

Do you need to know those basic concepts? Or is it like driving a car — you can be a good driver, without knowing what a carburetor is? To some extent, it is more and more like driving a car. We don’t need to know anything about bits and bytes and how computers work at a low level. But we *do* need to know what wheels and brakes are. The mental model that we hold is in our physical memory. We turn the steering wheel, the wheels shift, we can picture the wheels shifting, and then the car physically turns. To be a good end user of computer applications, I think that people need to create a similar mental geography. Maps and diagrams and metaphors can really help with that.

So here is my list of things to teach people who use computers a lot, but who are flailing.

Keyboard shortcuts:

– open, close, minimize a window or tab
– open, close, minimize an application
– find, select, copy, paste
– my tabs, let me show you them
– switch between applications or windows
– search (a folder or hard drive)


– The difference between closing and minimizing.
– Noticing, or how to tell, if an application is already open
– You can keep many applications open at once
– Recent history, recently opened documents or apps


– where is stuff on your hard drive
– what is a hard drive? what servers are you using? what does that mean?
– files and folders and network places; draw diagrams

Often, I’d start out trying to help someone with a complex issue, like teaching them how to do a mail merge, or fiddle around with a FoxPro or Filemaker database, and I’d end up going back to square one to teach them some of these concepts.

As I ponder this I think of a counterexample to the “mental map / diagram” idea I’m suggesting. Years ago, my otherwise pretty awesome boss at a K-12 school wanted me to create a particular thing that I loathed on instinct. Any of you who have been web developers will know what I mean! The year, 1996; the thing, a web site that was all a visual metaphor. The home page for the school web site would be a picture of a classroom-ish-office, or an office-ish-classroom, and all the things you might want to do on the website would link from pictures, like if you wanted to send email there would be a little mailbox, or to look at the cafeteria menu, click on the apple on the teacher’s desk. If you wanted to look up some document or form, click on the filing cabinet.

Number one, this would have been dog slow in the early web, on the LC-II Macs we had in most classrooms, and for people at home who only had dialup. Number two, the idea that the happy shiny pictures would not scare off the little kids who couldn’t read yet was just dumb, because one layer past the main page and you’d get to text. It is no good to click a 10-pixel-wide image of a phone book, if what you get is then… a phone book! Which if you’re 5, you probably can’t read and don’t want to use anyway. But number three, the whole idea of this visual metaphor sucked. We have invented words, and language, for a good goddamned reason and that is because it rocks! It’s efficient and powerful. If I want to look up what an apple is, in an encyclopedia, I don’t want to be floating in cyberspace and vaguely “clicking” through a 3-D taxonomy of shapes until I narrow it down to red round-ish blobs. We have words, and indexes, and alphabetical order, and search algorithms, and the convention of hierarchical menus of things-one-can-do-on-web-sites, to help us. We have the ability to group words tightly, to cluster them, in ways that makes sense for words but not for images. I don’t want to have to click on visual images one by one to figure out where to find the staff directory. I can scan a page of text very quickly to find that. Even much the most basic international symbols meant to bridge across cultures and languages are not obvious, and must be learned in context!

Possibly this is a bad story to tell because the end of the story is that when they did not listen to my objections, I mulishly ignored and resisted the Classroom Visual Home Page and instead just went off and made a plain, kick-ass, really slick and clean, page that did everything they really wanted and not what was coming out of their mouths, and that fit the specifications for dialup and legacy computers. And they used it for the next eight years. Which, while I am proud of it, maybe shows a bit too much about what it is like to have me work for you. You can’t always get what you want, but you get what you need.

Better Firefox, and a free makeover

I’m still halfway with a toe in poet-y land where everything is made of words and reality is very thin. It’s like swimming around in beautiful chaos! I love getting into that state of mind.

At the same time I’m messing about with techie things and it’s been a sort of cleanup week for me, as if it’s even more important for me to establish Order in the midst of my poety chaos.

I got fed up with my 8000+ emails in my Thunderbird inbox. I switched from using Pine about a year ago. And don’t get me started on how hard it was to get me even to the Pine level. I was very conservative and grumpy about it! Dammit, mm was good enough for me in 1989 and it was good enough for me in 1999! Anyway, my Thunderbird filters stopped working, and my inbox got goddamned huge. At times it has hit 20K. Finally, I gave up. I moved everything to a totally lame “2007 Inbox” folder. Voila! I’m at 0! As new flows in, I’ll construct new filters. And if I feel especially virtuous, I’ll go bulldozing through those 8000 old-inbox messages and put them away in logical places.

Search in Thunderbird still gives me hives. It starts searching the earliest emails first, and since I imported everything since 2003, holy hell it takes a long time to find the thing I filed away somewhere last month! Chug chug chug twiddle twiddle… sigh…

Still, it’s been pretty decent so far. I’m happy with it, though still wondering if I would be better off sending everything first to Gmail and then forwarding it on. Then I’d have it all two places without having to deal with IMAP.

My sister passed me a link today to some mozilla forum discussion about a bug with Firefox, Flash, and Ajax. Yeah I had KIND OF NOTICED. Ready to throw my computer out the window over here if it hangs one more time while I’m surfing around, hanging and chugging up my CPU without rhyme or reason. The links were all to PC/Ajax bug discussions, but here I am running FF with “Activity Monitor” up, because running top in a term window just makes the cpu usage problem worse, but with Activity Monitor I can sometimes kill Firefox before my whole machine crashes and I have to hard restart.

A few poking-around searches and I got to this repository of Firefox builds including ones for Intel Macs. So far I haven’t crashed today… huzzah. What will happen? Will it delight my heart? Will it bear all the weight I pile upon its back?

I’ve been using Desktop Manager (inspired by Skud). With this I can set up many different desktops and rotate between them, which is perfect! It’s rad! It’s not totally reliable but that doesn’t matter. I miss my old techie jobs where I would have 3 machines; a Mac, a PC, and an old Sun server. It felt like having a fabulous command center to swivel about and have all different junk set up on each computer. Plus on the Sun I’d have XWindow and 4 different desktops where I did all the real work. Anyway, now I have one small laptop, plus Desktop Manager. It’s nifty. At first I was mildly annoyed that I couldn’t get “move this window to Desktop 3” to work. Then I figured out I could just minimize it, go to 3 with a keystroke, and re open those windows with Quicksilver, which is relatively painless — I can train my hands to do it, like playing the piano. Mousing and trackpads suck because you can’t get that finger memory really working.

Mmmmm, Quicksilver. It haunts me. I am only scratching the surface of its beautifulness. It makes me so happy. It’s elegant! It feels like a powerful beast waiting to be tamed and taught tricks! So far I only really use it to switch and open apps. But, if I wanted to make some more nifty productivity stuff, Quicksilver is probably where I’d start. Danny babbled a bit to me about writing Applescripts to do various things. Applescript has never appealed to me. Maybe.

Meanwhile, at work yesterday Pete showed me YubNub so I’m in command line/ keystroke heaven. Now I can command-K up to the toolbar and I’ve got a bazillion useful shortcuts predefined.

You’d think that’s enough new stuff. But I have all these nagging projects. I spent some time at 7am this morning dicking around with me and Laura‘s Mediawiki install which has had annoying blanking and nonsense-insertion vandal attacks lately. As I looked around on the net I came across an article by WikiAngela that made great sense. I agree, it is better to leave a wiki open to anonymous edits! Then I came across Bad Behavior, a blacklist/whitelist application that I could certainly use on some blogs as well. Finally I ended up reading an incredibly useful article, Blocking Spam in Mediawiki. I did a bunch of it while Laura and I knitted our brows over permissions and group problems on the server. (Note: ConfirmEdit.php has a bug which breaks when it gets urls with a trailing backslash.) Oh man! Thank you for that excellent, brief, practical guide. Even if I cracked up hysterically laughing at your Orgasmosocialism page… OMG. Somehow “destroying the patriarchal institution of marriage and monogamy” was left off this dude’s list of the utopia which eliminates all social and political barriers to “the development of intimate relationships between consenting parties”.

Then I spent most of the rest of the day actually working. No really! It’s not just that my coworkers might read this! Except for when I went out for pie and bacon and the Bad Ass Mama’s Coffee Hour! I can prove it because finally this is up on SourceForge. I need to wrassle the ginormous release notes and bug fixes into a more news-like blog post and announcement for email lists. But it is nice to have it more or less out there for consumption. Yesterday I was melting down at the thought that I was stuck. But actually it was very very almost done, and things were fine. Why always with the last minute tearing out of my hair. I wish I hadn’t spazzed about it! At least not in front of people.

I leave you with this final, snarky, juicy thought as a reward for reading all the way to the end of this post. On a wonderful mailing list that I love dearly that shall not be named there was a long serious thread about this article on a nerd auction. The Washington State University LUG is auctioning themselves off at a Nerd Auction, to sorority girls, offering to fix their computers in exchange for a makeover. I cannot wait for the video. My god. I mean I am going to buy a plane ticket and quickly join the WSULUG. A lightning-smart hot chick in a pink sweater will buy me, and I will fix her computer. I will totally impress her with Quicksilver and Yubnub. Then, the (mutual) makeover, with a lot of giggling. Hey! Why not just sleep over in the sorority house? Geek slumber party! They’ll all end up with funny colored hair and will start wearing Leatherman tools on their belts, while I’ll come out of it all dishevelled, with lipstick all over my shoulders and a kick ass pedicure. Screw you nerds I am stealin all ur wimminz…

And then afterwards when all the ditzy sorority girls naturally reject the pale weedy glasses-taped-together nerd boys, I will be around the next day to comfort them…so I’d get the action from repressed, desperate nerds too. What a great setup!

“You can buy a nerd and he’ll fix your computer, help you with stats homework, or if you’re really adventurous, take you to dinner!”

My actual answer to that is unprintable and many-leveled and includes a snarling declaration of the actual meaning of Adventure.

No, seriously. The whole idea is kind of funny and yet pisses me off big time. I love the comment from this WSU mom of a geek daughter:

Do a search on world of warcraft and you will be loaded with girls who have no idea that WSU has great computer science department with a sense of bizarre humor.
Hell, if you had had a booth showing your online programs (assuming) for the stuff she does (which I don’t do…like Maya, etc.,etc., she might take an interest in her mother’s old school. Or maybe you are all Alliance and not Horde. Or are you all waiting for Halo 3. She lives on Newegg and is building her latest and greatest computer as we speak and would never ever join a sorority.

What a taunt! Hahaha!

Seriously again, the auction PR stunt plays up the very stereotypes they are trying to fight. Another comment points out,

Seriously, people, you wonder why you need this much press to get a woman to come within 10 feet of your sorry selves? This brings back every sexist or otherwise slimy incident I experienced studying engineering. . .

I have to agree, although I love ridiculous fun and can see that this LUG thought it was playing with stereotypes, not playing them up. I wish them success in that goal. And, presuming human decency from the bulk of them, I understand the lure of the spectacle and of publicity and of a joke. However, the impression I get is also that as a woman I am expected by their department’s culture to laugh and go along with degrading stereotypes of my gender.

But, I hope that the end result is that the CS department asks women why they don’t enter or stick with CS as a major, and listens to the answers, and acts on that. Or, they could go read the many studies which address exactly that question. How about this one by Ellen Spertus, Why Are There So Few Female Computer Scientists? . How about reading She’s Such a Geek, a book of fabulous essays by geeky women, in which nearly every essay explains the barriers and annoyances we face. Or this paper by Tracy Camp, The Incredible Shrinking Pipeline. There are a zillion more.

Maybe if they paint the Computer Science Dept. building pink? That might help?

I wonder what they do to encourage racial minorities to enroll… “Nerds” fix your computer, and you teach them to… what? What race and stereotype spring to your mind? Think that event would happen? No? Then why is this one okay?

Despite everything I have ever experienced and said about geek culture and gender, here is the key. I still expect geeks to be better than this. My techno utopia has got some basic feminism in it and so do a lot of other people’s.

Pink and sparkly

Okay on the one hand, Geek Girl Bingo. Pink, sparkly, cute, colour choice, stereotype city. I am totally down with calling people on their constant application of these ideas to femininity.

On the other hand, I kind of want this. On the substrate of the pink and sparkly Hello Kitty laptop, I would add a million bad attitude stickers, and it would be glorious. I could mod my Hello Kitty with some green tentacles to make a Hello Cthulhu. It’s kind of a problem.

Clearly my mind is not free from colonization.

Maker faire: Computer sculpture

I saw countless cool things at Maker Faire today. The booth was one of the coolest. The dude there, Andrew Werby, let me sit there and play with a demo for a while. There was a pre-defined 3-D object on the screen, a sort of smooth, soft, spongy blob. With a pen on an articulated arm, like one of those adjustable desk lamps, I could “feel” the object’s surface and by pressing a button, push into it and sculpt it.

This was uncanny! The kinesthetic sense, the resistance in the pen in my hand, was just perfect. It was as if I was feeling and manipulating a real object. It was a bit like punching a blunt tool, a stylus, through thick foamy stuff; I thought of hot wire and foam carving kits.

At some point, I carved through the blob into the center, and the tool fell through into a sort of cave. I could feel around inside the object and visualize it in my head. There were multiple exit holes in the back, where I couldn’t see, that other people doing the demo before me must have made. The sensation reminded me uncannily of the numb feeling of pressure that I have had during surgical procedures. The tool also looked like and behaved like an instrument i held in my hand — except I could pass it through the object. So the tip had all the sensation and the handle was ghostly and non-existent. I had sensation, without having any hands. I could imagine surgeons really doing “Fantastic Voyage” type of operations this way. But it should also be a tool that game designers use for character and world building. I can’t imagine artists not loving this tool!

I have never felt something on a computer, a thing that I couldn’t see. My head exploded with thoughts of designing cool video games for visually impaired people. Mazes and thought puzzles and art pieces.

There was more to Andrew’s set of tools; you could sculpt, and then 3-d print your objects. I was blown away so completely by the kinesthetic 3-d modeling, I didn’t pay attention to the rest.
