awesome part is the custom-designed circuit board that accompanies the CD and lists the tracks while doubling as a theremin instrument with headphone jack -- all in a standard-size jewel case. Hit the on button and start making 'music' by waving your hand in front of the light sensors. Sure it sounds a bit like you're squeezing air through a pinched balloon and it costs $50 ($10 for CD-only or $25 for a Pocket Edition), but hey, give this guy some credit for innovation. Check the video after the break, you will believe at the 1-minute mark.
