Warning: I couldn't hear the audio as I was playing, so my rhythm's not that great. Double whammy: I haven't been practicing.
This projection-mapped Kinect-based drum machine was built with a simple 4:3 grid made out of wood. It was then painted white for maximum brightness and hung from a curtain rod attached to tripods. With the Kinect and projector aligned in front of the physical structure, it becomes easy to lay down a sweet beat by punching through the openings.
