The Reactive Cube, by Graham Plumb, is an acrylic cube filled with water and light. It was designed to transform digital images into apparently physical objects. A 2D image is projected through a mass of water mixed with a specially formulated emulsion of oil.

The light is captured by the oil and appears to become a real object. Each version of the series is based on a particular form of interaction. Some cubes are reactive to sound, another to gesture, to the breath of someone from the audience, etc.

Graham Plumb will be at Dorkbot San Francisco, on 30 November 2005.
