Australian artist Peter Hennessey turned plain ol' plywood into amazing works of art. I'm sure you can draw all sorts of inference from his re-creation of high-tech spacecrafts using the simplest of all material (wood - plywood at that), but don't let that detract you from enjoying his masterpieces:

My Lunar Rover (2005)

Trivia for you: the Lunar Rover AKA Moon Buggy was built by GM. It worked beautifully for Apollo 15 mission, but during the next mission, in a true GM moment, the rover's rear fender fell off. Astronauts had to make an emergency repair with duct tape, maps, and clamps. (See: 10 Things You Didn't Know About General Motors)

My Voyager (2004)
