The Air Guitar Pro is a guitar designed for air guitarists that actually plays music. You hold the chord buttons on the fretboard and then strum the air. Infrared sensors in the neck detect the hand motions and it plays the note. If you're not into playing your own music it also comes with preloaded tracks. The final product will ship in July but importer HimeyaShop is taking pre-orders now for about $27. Although actually playing music kind of defeats the purpose of an air guitar. It's like having an imaginary friend who's also a real person. Who wants that!
