This is truly crazy! A 20 year old has built a drivable 500,000 piece Lego car.

500,000 pieces of those well known plastic blocks - and four engines with 256 pistons that run on compressed air. It was designed and built by 20 year old Raul Oaida in twenty months after he and a partner raised tens of thousands of dollars from Aussie backers. It will only cruise at 12-17 mph hour, but as shown in the video, you probably wouldn't want to go any faster.
