I'm almost finished with a poster that shows Turing machine computations visually, as sets of Wang Tiles (http://en.wikipedia.org/wiki/Wang_tile). There's a little bit more to it than just visualization -- by following simple placement rules (match colors together) you're actually *performing* the computation; it's even been shown that if you structure DNA molecules as Wang Tiles, they will self-assemble into computations like the ones show here.
Anyway, since this is the first time I've done anything remotely design-related, I'd appreciate comments on the layout, fonts, colors, etc.! I'm currently in the process of redoing the fonts in the legend, as the Python Imaging Library doesn't do hinting/antialiasing very well.
A larger version is here: http://i.imgur.com/4630U.png (hopefully I won't get in trouble for posting that?)
Criticism, however harsh, is welcome
