Angela Bulloch's sculptures and installations unite elements of architecture, industrial design, new media, and viewer interaction. She is best known for her "pixel boxes," infinitely programmable illuminated boxes containing three fluorescent tubes capable of creating all 16 million colors of a standard computer screen. In her pixel boxes, Bulloch combines individual cubes into modular systems, as in Z-Point (2001), comprising 48 stacked boxes that create a looped abstraction of the explosion scene from Michelangelo Antonioni’s 1970 film Zabriskie Point. Other pixel boxes and sound installations explore the effects of environmental stimulus by incorporating variations that are activated by the viewer, such as in The Laughing Crowd Sound Piece (1990) where walking through a room triggers canned laughter.
