It is pretty interesting how simple rules can give rise to complexity. RIP Conway.
- For a cell that is 'populated':
- Each cell with one or no neighbors dies, as if by solitude.
- Each cell with four or more neighbors dies, as if by overpopulation.
- Each cell with two or three neighbors survives.
- For a space that is 'empty' or 'unpopulated'
- Each cell with three neighbors becomes populated.
