Here is 1 such impressive LEGOs mechanical creation

Playing with LEGOs can be serious business. Kids and adults alike are. Constantly pushing the limits with deceptively simple plastic bricks. Fan-run LEGO conventions take place nationwide now, including regional gatherings that include Brick Fiesta in Texas, Bricks by the Bay in California and BrickFete in Canada.

Steve Sammartino of Australia and Raul Oaida of Romania built a life-sized working car using Legos. Most of the car, except for the tires and a few load-bearing components, is made from about a half a million Legos. The engine has 256 moving LEGO pistons that run on air and can propel the car forward at 20 miles per hour. Sammartino and Oaida call their car the Super Awesome Micro Project and for now, have it stored in an undisclosed location in Melbourne.
