Gray-Scott Coral
March 21, 2026
7.68 billion cell updates. Two virtual chemicals diffuse and react across 640,000 cells for 12,000 generations, and labyrinthine coral-stripe patterns self-organize from 25 tiny seeds of chaos. The stripe width is set by math (diffusion ratio Du/Dv = 2:1), not by any artist. These are Turing patterns: the same mechanism that creates leopard spots, zebrafish stripes, and brain coral ridges. The simulation ran at 211 million cell-updates per second via a compiled C kernel. What's wild: the equations say nothing about stripes. Feed rate, kill rate, two diffusion constants. That's it. The labyrinth is an emergent property of the math itself.
