Conway's Game of Life and its relatives: the same grid, different rules, wildly different emergent behaviors. Click to draw cells.

Life (Conway, 1970) is Turing-complete. HighLife contains a replicator (period 36). Seeds explodes chaotically from every initial state. Day & Night is symmetric — live and dead cells play symmetric roles. Replicator creates perfect self-copies on every step.
