These include works made of metal, wood, acrylic, or foundobjects, and often use laser-cutting or rapid prototyping technologies intheir realization. Also shown will be brief videos of the assembly ofthree large commissions: a six-foot sculpture constructed from 642 CDROMsin the Computer Science building at U.C. Berkeley, a five-foot sculptureconstructed at a community "barn raising" event, and a "Salamanders"sculpture assembled by students when he was artist in residence at MIT.Mathematical and computer science aspects of these designs will bediscussed.
