The strangest group since The Residents, the Blue Man Group has taken to musical toys. The toy is all PVC mixed with cool styling and some electronics, featuring new proximity sensor technology, pre-programmed songs and interchangeable instrument sounds to enable kids to mix and layer music with a simple wave of their hands. The Percussion Tubes model has a slot (the little green drawer on the right) for an iPod, which can play out of the speakers so kids can jam along with their favorite tracks.
