Two chemicals on a torus. U is consumed by V; V dies on its own. Diffuse them, and life-like patterns appear — spots, stripes, mitosis — every frame computed live on the GPU.

Alan Turing wrote down this equation in 1952 to ask how a zebra gets its stripes. The chemistry was wrong; the mathematics was not.
