What you’re watching is a piece by artist Chris Burden called Metropolis II, in which every hour 100,000 cars pass through the city of wood block, tiles, Legos and Lincoln Logs. It’s a follow up to Burden’s Metropolis I, which was built on a similar concept but employed only 80 cars. Metropolis II is currently being constructed at the Los Angeles County Museum of Art.
