Art installation moves 100,000 toy cars an hour

IT'S NO PICASSO, but this installation by conceptual artist Chris Burden certainly has the potential to be moving. Called Metropolis II, this amazing construction took Chris and his chief engineer four years to design and create and expands significantly on Metropolis I - the latest version has 18 roadways including one six-lane carriageway. It also has a rail network with HO-scale model trains, and running at capacity it pumps 100,000 cars around its network at a scale speed of 230mph.
