Musical interface that just begs to be played with

The PocoPoco is a musical interface/controller that is almost a minimalistic work of art. You control the sounds by manipulating the custom-designed solenoids with embedded sensors and lights. You can push on the solenoid to enable that sequencer step, hold the cylinder to hold a note, and turn the cylinder to affect the tone (filter/fx/pitch/etc)

I get a sense of enjoyment from just watching the tactile-ness of people playing it – I can see how it would be a great performance device.
