256 rules. Each one: a 1×N row of cells, a neighborhood of 3, a lookup table. Time flows downward. Some rules die immediately. Some fill the canvas solid. Rule 30 produces randomness. Rule 110 is Turing-complete. The same substrate — eight bits of rule, a row of cells — yields anything from nothing to everything.
