Mushroom Life is a very interesting flash application that requires a lot of clicking. The application shows a very nicely laid out 3d area that when you click mushrooms grow. However, there are rules to this game as follows: For each generation, a mushroom with 1 or 0 neighbor dies (loneliness), a mushroom with 4 or more neighbors dies (overcrowding), a mushroom with 2 or 3 neighbors survives (stability), an empty space with 3 neighbors sprouts a new mushroom (birth). Try it out, see how much mush you can make.
