A German designer, who is well known for his unique musical inventions, has now placed a midi controller into a sofa. You use your buttocks to control the music. Each cushion of the couch contains three output controls for the midi system—leaning left, right, and back all produce their individual notes. A fourth musical note is optional depending on what you had for lunch. Bonus: Check out some of his other cool inventions including a Commodore 64 synthesizer.
