I made a toy, Whac-A-Mole. It is two players game toy. One player controls the mole up and down via iPhone, another player hits the mole with a paper mallet. When you successfully hit the mole, it makes a sound. The players play against; one player try to hit the mole and make a sound, but another player tricks. This idea came from class lessons: automata, servo, blue tooth shield, and xcode.
