'One Minute Communication - 3D' (2004) by Daniel Jackson. The sculpture consists of two aluminium spheres suspended in a glass and white enamelled steel cabinet. The spheres are in conversation. An artificial-life program controls the conversation which is relayed through the movement of the 2 spheres. The AI nature of the software dictates that the conversation will never be repeated - the gesture speed, the positioning and the length of movement are all determined by a combination of randomness and probability.
