GeoPatternLabLangton's Ant
A tiny ant that turns on colors and builds surprising highways.
Two rules, one ant: it turns, flips the tile, and steps - eventually building an ordered highway.
About Langton's Ant
Langton's Ant follows two simple rules yet produces astonishing complexity: it turns, flips the cell under it, and steps forward, eventually building an ordered 'highway' out of chaos. Choose multi-color turn rules (RL, RLR, LLRR and more), speed the ant up to thousands of steps per second, and export a high-resolution PNG.
