The theremin is an interesting instrument; brilliant in conception, difficult to play and limited in control. The Thimbletron gloves developed by TradeMark G of the Evolution Control Committee are a fascinating user-interface, limited to the number of feasable fingertip-touch combinations, and how fast can you mime "The Itsy-Bitsy Spider?"
Imogen Heap plays a dizzying array of instruments, some of them via varied and wondrous UIs. Her latest notion is "musical gloves," using the entire range of gestural motions: driving a modern synth, it's Theremin times Thimbletron, cubed!* The UI options are huge. The end result crosses playing an instrument with dance -- at least with the software she's running.
You might do something else, and you have a chance to find out: the software's open-source and the gloves are getting Kickstartered!
That's (Ther * Thimb)^3, I mean, and possibly an understatement.
