Cellular Automata
Watch small rules grow into surprising patterns.
Generation: 30
A simplified teaching model. Cells beyond the edges are empty.
How to play
Tap cells to toggle them. Edit the top row to regrow 30 generations in 1D. Changing rules clears its history. The 2D garden includes still, oscillating and diagonally moving patterns. Arrow keys select a cell; Enter toggles it.

Each rule bit specifies the output for one of eight three-cell patterns. The 1D view has 61 cells and shows 30–60 generations. The 2D board is 20×20, so shapes reaching an edge behave differently from an infinite grid.
