From the Audio Cubes site:
This is a musical interface I have been working on over the past years. It is a tangible user interface (TUI) consisting of a number of cubes made out of a plastic material. Each cube contains a digital signal processor (DSP) with optical sensors and emitters (infrared, red, green and blue LEDs). The sensors and emitters receive and send audio signals which are generated or processed by the signal processor in the cube. Each cube is powered by a rechargeable battery pack. By positioning the cubes relative to each other and moving them around, a signal processing network can be created. A musician can use this interface to learn a new way of interacting with sound and music.
OK, so technically, this should probably be considered more of an audio/sound engineering creation, but optical sensors and emitters (infrared, red, green and blue LEDs) ARE involved, the cubes are cool, and, if they can change colors to the music, then I definitely want a set.
