Kee, designed by Shira Miasnik , is a motion-based digital music instrument.
The user modifies the digital output by tilting and rotating the wooden disk.
Movements can define endless parameters: manipulating Kee in different directions, angles and speed changes different qualities of the animation. Pressing the logo button modifies the presets which define the changes in the animation.
It is fairly hard to say from the video how exactly it works, but it seems like a nice combination of "digital" with "retro".
