Sharks and Fish on the Planet of Wator @brainwagon

Uploaded December 2009 | Updated September 2026, 49 minutes ago

In December of 1984, A. K. Dewdney first described a fun little programming exercise: a simulation of sharks and fishes in a toroidal world called Wa-Tor. I've implemented this for fun a couple of times over the years, on platforms as diverse as my old Atari 400, a VAX 11/750, and now, multicore Intel boxes. This is the output from a simple implementation I did in Python. Enjoy.

$The HOPALONG Orbit Fractal An animation, generated by a custom rendering hack, and encoded using FFMPEG. I kind of wish the image wasnt jumping around so much: unlike many IFS fractals, this orbit fractal generates fairly different distributions depending on pretty much the least significant bits of any of the control parameters. Still, pretty neat.$
