Hong Kong-based modulogeek has taken his toddler’s toy glockenspiel and created an servo-motor based control for it. He has then fused this with a monome interface device which is controlled by the Raspberry Pi running the Python sequencer code. Together, he has created a lovely musical instrument that is part tech, part art piece. The code is available here and you can see it in action above.

Thanks to Pi Weekly for spotting this one!
