A palm-sized sphere containing an Arduino Uno, accelerometer and Bluetooth transmitter. Custom software maps orientation to a pitch space by assigning pitches to a face of an equivalently oriented polyhedron. Notes are triggered when different faces move through a fixed axis, with further processing effects being controlled through acceleration of the sphere. (Arduino, Processing, Ableton Live, Max4Live).

The project was presented as part of Cave Of Sounds.
