That reminds me, back during the Tamagotchi craze (which coincided with the Pokemon craze) there was a virtual pet Pikachu that rewarded you for walking (it was a pedometer) and the screen would show Pikachu walking while you were. It was pretty cute. Well, it wasn't long before my little brother figured out how to "cheat" He put it on the washer. (I think dryer worked as well)
