This fellow W.E. Johns has got the Geekdad spirit.
It is powered by an electric motor, and controled with an X-arcade joystick. But the real kicker are the working wooden catepillar treads. Whahoooooo!

The guy offers a very detailed step-by-step build out on his site, and sells plans if you want them. His site called the Gizmologist's Liar has a bunch of other projects -- like a homemade paint ball gun -- and tons of maker hints. Cool guy.
