Unlimited Automata

Conway's Game of Life is one rule in one family of twelve. Browse them, draw into any of them, and wind any generation back. TWELVE FAMILIES Life — Conway, HighLife, Day & Night, Seeds, and the rest of the birth-and-survival space.

Generations and Larger than Life — cells fade over time; bigger neighbourhoods make swimming blobs. All 256 Wolfram rules — one row of cells, time running down the screen. Turmites, reversible blocks, and WireWorld — Langton's ant, rules that run backwards, and a grid wired for logic. Excitable media, sandpiles, forest fires — spirals, avalanches, and spreading fire. Continuous fields — Lenia, SmoothLife, and Gray–Scott. WATCH IT, AND WIND IT BACK The slider seeks — drag it back and the earlier generation returns exactly. A frame at a time — step forward…
