When does playing with toys become an artform? When you stop calling it a Hot Wheels track and instead dub it kinetic sculpture, apparently. Chris Burden has crossed the admittedly hazy line between Hot Wheels fan and Hot Wheels artist with Metropolis II, a super-massive construction that runs 1100 toy cars in constant motion over its custom-built tracks. The project took four years for 12 people to build.
