Life

Life is an implementation of Conway's Game of Life. In the game the player can draw patterns which evolve using the following rules:

• Any live cell with fewer than two live neighbours dies, as if caused by under-population.
• Any live cell with two or three live neighbours lives on to the next generation.
• Any live cell with more than three live neighbours dies, as if by overcrowding.
• Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction.

The grid wraps around at both the top and the bottom.
