Metropolis 2 at LACMA is complex, large-scale kinetic sculpture modeled after a fast-paced modern city. The armature of the piece is constructed of steel beams, forming an eclectic grid interwoven with an elaborate system of eighteen roadways, including a six-lane freeway, train tracks, and hundreds of buildings. 1,100 miniature toy cars speed through the city at 240 scale miles per hour on the specially designed plastic roadways. Every hour, the equivalent of approximately 100,000 cars circulates through the sculpture.
