Lego's had a separate line just for the truly, irredeemably smitten gearhead for years, the Technic line. Where conventional Legos were defined by bricks, Technics went beyond mere masonry into the realm of engineering, and was full of moving gears and belts and pistons and other amazing stuff. Now there's a book crammed full of it.
The book, Incredible Lego Technic: Cars, Trucks, Robots & More!, has lots of incredible Lego Technic cars to scrutinize and drool over and plan your own build around. This book looks like an ideal geek-out tool. Check out some of these stills, if that video wasn't enough. It's the details that get me, the clever repurposing of the parts, like forming the Shelby Cobra badge with those three little lego parts. Oh boy.
