From environmental installation "Photon Voice", CAVS/M.I.T., NEA Inter-arts Project, "Desert Sun/Desert Moon", Lone Pine, CA. Filmed by "Smithsonian World" June, 1986. In Collaboration with the Laura Knott Dance Company. Light encoding and transmitting installation /performance designed to encode sound, images, and motion into sunlight. Details of sun tracking sculpture, and receiving stations that decode the sunlight's "radiation pressure" to construct microscopic sculptural forms from the interaction of photons with electrons in matter.
