 Each cell is now given a set of rules: Each rule tells the cell to look at 4 of its nearest neighbors and count the number of white cells. If there are more than 3 white cells surrounding it, it should change its color to black.
-Imagine that for the grid above you now ask each cell to count the cells around it and remember which color it should become; and when you give the signal "GO" all cells should change their color to the remembered color.
