Take an Arduino, accelerometer and gyroscope-powered VR glove, some custom software, a projector and some funky interiors and you've got yourself the most futuristic game of Pong I've ever seen. Spoiler: the ball actually bounces off the stairs.
It's part of a project titled "Ping Pong Game with Physical boundaries on an architectural wall", which recently swept the "Boring Name For an Awesome Idea" awards. Now if they could get something similar going for Contra, I'll be all set. [SlashGear]
