The Los Angeles County Museum of Art has got itself a new toy. Or, to be more precise, it's got itself a whole fleet of Hot Wheels mini speedsters, courtesy of one Chris Burden. He's the gent responsible for dreaming up Metropolis II, the above interwoven set of tracks and circuits, which is populated with 1,200 "custom designed" cars, 13 toy trains, and some assorted scenery built out of Lego, tiles, and wood blocks. We're not sure whether it's intended to represent the daily rat race we call modern life or if it's simply a boyish dream turned real -- decide for yourself after watching the video after the break.
