Game — Moon Breaker
It may use an augmented ping pong table, but Moon Breaker is quite different from actual ping pong. Moon Breaker is a game made in Processing and winner of the Ping Pong Plus Plus Game Jam. It uses a ping pong table augmented with force sensors to detect where a ball lands and an overhead projector to display visualizations (or in this case the Moon Breaker game).
The goal is fairly simple, do everything in your power to protect your half of the moon while breaking your opponent's half. Wherever the ping pong ball lands, an explosion occurs and a portion of the nearby moon is damaged. Run out of moon to protect and it's game over!
