Metropolis II, built by artist Chris Burden and a team of eight helpers, is a representation of road traffic in Los Angeles. Started in 2006, and still a work in progress, it features 1200 custom-made Hot Wheels cars, 18 lanes, Lego buildings and 13 toy trains.
In “Metropolis II,” by [Burden’s] calculation, “every hour 100,000 cars circulate through the city,” Mr. Burden said. “It has an audio quality to it. When you have 1,200 cars circulating it mimics a real freeway. It’s quite intense.”
