“In an innovative fusion of modern dance and high technology, Tricia Brown is collaborating with a computer on “how long does the subject linger on the edge of the volume …,” a 30-minute work for seven dancers and animated graphics. Ms. Brown has choreographed the dance. And the computer, driven by an artist-designed artificial-intelligence software program that responds instantly to the dancers’ movements, draws graphics that are projected on a transparent screen in front of the stage.”
