Metropolis II is kinetic sculpture by artist Chris Burden. It's 10 feet tall, 28 feet wide, and features more than 1,100 toy cars racing around 18 lanes of mini-freeway. It took the artist and his assistants more than four years to complete, and has now sold for millions of dollars and is available for public viewing at the Los Angeles Country Museum of Art.
This isn't some geek playing with toys. Burden is an established sculptural and performance artist who's created some amazing works over the last few decades.
gosupermarche has created a short documentary about the piece, which is definitely worth your time.
