Conway's Game of Life

"Life, uh... finds a way." — Dr. Ian Malcolm

Conway's Game of Life is a two-state two-dimensional cellular automaton, with the following rules

1. A living cell dies if it has less than two living neighbours
2. A living cell dies if it has more than three living neighbours
3. A living cell stays alive if it has between two and three living neighbours
4. A dead cell revives if it has exactly three living neighbours

From these four simple rules, complex patterns and behaviour result
