The Game of Life :
An empty cell with exactly 3 (of 8 possible) living neighbors will come alive.
A living cell with less than 2 or more than 3 living neighbors will die.

Click a grid box to toggle a cell dead or alive.
Click the green (go) box to advance from one generation to the next.
Click the red box to make the grid denser.
Click the yellow box to make the grid coarser.
Normally each click of the green (go) box advances the game a single generation. This can be changed to 10 (and back to 1) by clicking the white box.
