"Penrose Tiling"
For this one, I dug around in my hard drive, and found an old bit of code that generated Penrose tilings. The code starts with a configuration of triangles, a "wheel" of isosceles triangles, and then subdivides them based on the subdivision rules here: http://www.math.ubc.ca/~cass/courses/m308-02b/projects/schweber/penrose.html This guarantees a valid Penrose tiling without having to do the hard job of extending the tiling from a seed rhombus.
I subdivided a few times to get the density I liked, and then inset each rhombus by 10% so that things wouldn't touch.
Tools Used: AxiDraw, Pentel .5mm pen, old Penrose Tiling code I had written previously
Languages Used: Python
Development Time: ~1.5 hours
Drawing Time: ~10 minutes
What's Generative Here: Not a lot, really - the initial configuration was selected by hand. Maybe the subdivision rules can be considered generative. I want to revisit this with a random zoom into the initial configuration (which is what the original code did, but I didn't port the random bits).
