Seeing the pictures is one thing, I've seen the real stuff. My Master's Degree was paid for by NASA. The research I was working on involved robotics (I was doing all the AI stuff) and I had a presentation with my Professor at JPL. They gave us a tour and had some of the stuff in a display case. It was carved out to spell JPL. It is amazing looking. I always likened it to when Scooby Doo would cut out a donut from fog in the old cartoons.
