i've long time been interested in algorithmic mathematical art. That is, mathematical or algorithmic visual art works that are generated by computer such that the program's source code reflects the algorithmic essence of the visual quality in the art work. (for detail, see Algorithmic Mathematical Art at http://xahlee.org/Periodic_dosage_dir/t1/20040113_cmaci_larcu.html )
Mathematica programers, especially Michael Trott, have been doing algorithmic mathematical art since the early 1990s. I started my programing career with Mathematica in 1995, and since late 1990s i've been searching for such work outside of Mathematica, but it is almost non-existent. (maybe less than 10 cases that i know of, and most their code do not capture the algorithmic nature of the rendered art.) The one most prominent mention of it is in chapter 2 of the book Structure and Interpretation of Computer Programs by Hal Abelson et al. anyway, today i ran into this page by Frank Buß http://www.frank-buss.de/lisp/functional.html which used the idea in the book to render a traditional Escher's tiling piece. I hope this will help the spread of algorithmic mathematical art. If you find other algorithmic mathematical art, please let me know!
