that instrument is an awful lot like an iPad app that Jordan Rudess was involved with. It's called GEO-SYNTH. Very similar concept, but obviously scaled down to the size of an iPad screen

I think it's a free app.

I'm still waiting for the inevitable adaptation of the idea to a smooth guitar neck. There are already midi guitars that trigger the note by tapping the neck, but a smooth neck like that keyboard would allow a much wider range of nuanced CC in real time.
