From the Fridays Are For Fun Archives - You're In Control

The You're In Control system uses an array of piezoelectric sensors mounted to the back of a urinal to detect the position of a stream of water, allowing a person to play a video game while peeing. A video monitor is mounted above the urinal, and position on the back of the urinal corresponds to position on the screen. We created a custom video game (our interpretation of the carnival game "whack-a-mole") in which the player attempted to hit hamsters as they flew out of one hole and into another hole in the ground. A successful hit would turn the hamster yellow, make it scream and spin out of control, and give the player ten points.
