Every little boy who has ever owned a Hot Wheels miniature car remembers how fun those things were to play with, whether you owned a circuit track or not. Artist Chris Burden has spent the last four years working on Metropolis II, an awe-inspiring miniature car circuit that will spark the interest of even the most mature grownup.

It’s called Metropolis II because Chris built another cool Hot Wheels circuit back in 2004, but compared to his first one, this latest project is superior in every way. It really lives up to its name, measuring an impressive 10-feet-tall by 28-feet-long and featuring 13 toy tracks and a gigantic car circuit with 18 lanes, winding around in a loop, around 30-40 skyscrapers. There are a total of 1,100 modified cars moving around Metropolis II, at any given time. Chris and his team inserted a small magnet on the underside of each car, so when they reach one of the circuit’s three conveyor belts, which also have magnets placed underneath, they get picked up and transported to a high point from where they are released and flow away.

According to Chris Burden, Metropolis II is ten times bigger than the original Metropolis and was conceived as a miniature representation of Los Angeles. Just recently completed, Metropolis II has already been sold for millions of dollars, but Burden says is also cost millions to complete and refine. Over the next few months it will be taken apart and properly packed in steel cages, where the parts shouldn’t move more than a 32nd of an inch, in order to keep everything running smoothly.

While it may not be as realistic-looking as the White Lake Formula One Ring built by James Michael Harlan, the Metropolis II is definitely one of the coolest things I have ever seen.
