Conway's Game of Life

Conway's Game of Life is a cellular automata with 4 simple rules: 

1. Any live cell with fewer than two live neighbors dies, as if 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 live neighbors dies, as if by overpopulation.
4. Any dead cell with exactly three live neighbors becomes a live cell, as if by reproduction.

This program lets you simulate this and create your own CGOL designs. You can save and load these to keep the ones you like best.
