Others may need an explanation, so here goes: The Tetrafol is a hand-held tangible electronic sound toy. Circuits enclosed by a wooden tetrahedron detect orientation and motion-gestures to modify the playback of a collection of Fol Chen's micro-compositions. Users can explore sound through objectual physical manipulation. The battery-powered device has its own internal speaker but can additionally be hooked up to a headphone or amplifier for broader consumption and recording purposes.
The circuit and firmware are based on open-source hardware and is itself published as open-source, allowing anyone interested to learn about its deepest inner-workings.
There are only 100 of these devices. You can buy one for $110 right now by clicking here. For now.
