pH (1990-93) was a multimedia project combining performance, installation, video and printed matter. The staging for pH was unique: the audience sat high above a narrow sixteen-meter white linoleum floor. A pair of computer-controlled truss beams continuously crisscrosses the set upstage and down, while beam-mounted slide projectors project images onto the floor "screen" and performers fight the implacable mechanical motions of the beams. Biography of the art collective and writings about the project are provided in the book.
