Anybody who built tracks for their Hot Wheels as a kid will drool when they see this incredible setup! Metropolis II is an amazing, kinetic work of art by Chris Burden that measures 20x30 feet, and features over 1200 matchbox cars that travel at speeds up to 200 scale mph. John Farrier first wrote about this spectacular feat of micro-engineering back in November of 2010, and now it can be seen, live in all its massive glory, at the Los Angeles County Museum of Art beginning this fall. Watch the short doc, made by the same folks who made Catfish, and you'll see just what the hype is all about.
