What self-respecting software developer hasn't built John Conway’s Game of Life? Click cells to toggle their life, click live (upper left) and see the rules of the universe play out. The universe’s rules are simple:

1. Any live cell with fewer than two live neighbors dies, as if caused by under-population.

2. Any live cell with two or three live neighbors lives on to the next generation.

3. Any live cell with more than three neighbors dies, as if by overcrowding.

4. Any dead cell with exactly three live neighbors becomes a live cell, as if by reproduction.
