Surfing around and found this. I think I will pre-order one, probably a one trick pony, but at that price you cant really go wrong.

WEIRD AND WONDERFUL SOUNDS AT YOUR FINGERTIPS

The Stylophone Theremin is a portable touch sensitive synthesizer that creates experimental sounds by detecting your movement. Wave your hand around its antenna, move its slider from side to side, and go over the edge with mad modulation, wobbly vibrato, and crunchy echoing delay for crazy, quirky, sci-fi sound creation.

Whether you’re a music maker, a beginner synth enthusiast, or you just want to have fun making noise, the Stylophone Theremin is a pitch only Theremin and takes the retro analog sound of a synth icon and makes it wilder than ever.
