Each team controls a fence that protects its cats by showing GREEN to raise the fence and RED
to lower it. A dog runs back and forth contolled by the computer. If the dog gets over or under the fence a cat jumps on him and a noisy ruckus ensues. They both go off the screen and the other team gets a point.
The amazing part of this game is that the decision about how high or low the fence moves is made instantly through
non-verbal communication. The effect is quite exciting and perfect for team building.
