Here are some images generated by an evolutionary-art generator I generated mostly in september 2001. You can click the pix for the genomes. An interesting feature of the representation is that it contains redundant information, so there's not a 1-1 genotype/phenotype correspondence. The program makes use of this to "compress" genomes before rendering. Currently, it's using a really naive and buggy interval-based bounding algorithm. The genomes shown here are the "uncompressed" versions.

mega-crufty code available here. it's bad C and really bad X. caveat whatever.

Dave also did some nifty evo art. It's funny how different our approaches were. He's one mad spirographer! That's here.
