Technology Review: Blogs: Mims's Bits: Robots as Art: The Serene Beauty of LumiBots: "Each 'bot is equipped with a tiny infrared light. As it drives itself across a glow-in-the-dark mat, this leaves a trail of visible phosphorescence. In the front of the bot, a light sensor helps the lumiBot follow any trail it encounters, its own or that of other lumiBots.

By both following an existing trail and reinforcing it by laying down a new one, or even refining it by taking shortcuts, just as real ants do, lumiBots, which have no memory, communicate elementary spatial information to one another and allow designs on the floor to arise by emergence, rather than the dictates of a pre-defined program."
