If a life-sized Lego car that actually drives and is powered by nothing but air doesn't sound cool enough, consider this: The project was funded in part through a single tweet.
The car runs on compressed air, is made up of more than 500,000 Legos and can cruise along at some 15 mph. It's the brainchild of Raul Oaida, a 20-year-old Romanian who previously launched a Lego shuttle into space.
