Artificial life on a closed surface of curved space.

Thousands of particles, one simple rule, and a universe shaped like a two-holed donut made of hyperbolic space. Runs live in your browser.

Particle Life is a famous toy universe. Coloured particles attract or repel each other according to a small table of numbers ("red likes green, green fears blue…"), and lifelike creatures emerge: cells, worms, hunters, membranes.

Look at the corners of the central octagon in the screenshot below: the same creature sits on all eight.
