Well done! More selection than drift, but that's me being an evolutionary biologist :D Loved the art (interesting placement of the third eye at times, ha). I _think_ I was starting to figure out some patterns but it was taking too long to generate the strings I needed (and I wasn't sure if there was a way to generate them less randomly, which then again wouldn't mimic drift). Nice submission, it was also fun to just button-mash generate a bunch of random cats.
