From the article: "What Are AudioCubes?

Audio Cubes were invented and are manufactured by Percussa, a small privately held company in Belgium. Each AudioCube is a portable self-contained computer that acts as a tangible interface. The cubes detect location, orientation, and distance information from your hands and/or other AudioCubes. This information (MIDI or OSC) is then routed to your favorite music application via free software that is provided by Percussa. The software runs both on MAC and PC. I'll be focusing on MIDI, Windows, Ableton Live, and the MIDI Bridge application in this review, but will offer a summary of other Percussa apps at the end of the review."
