Laser-projected images on moving steam screens, solar-tracked holograms, a 144-foot water prism and helium-lifted sky sculptures are some of the features of "Centerbeam," a kinetic performing group work exhibited at documenta 6in Kessel, Germany (1977) and on the National Mall in Washington, D.C. (1978). Its production involved the participation of 22 artists at MIT's Center for Advanced Visual Studies—as well as science and engineering consultants. These illustrations, essays, and biographical profiles of the contributors provide a history of the work, documenting the unusual collaborative process that brought it into being.
