I learned at an early age that I could make the things that I wanted. That's a very powerful thing to realize as a kid. LEGOs were a key part of that.

Back when I was a professional model-maker at Industrial Light & Magic, my specialty was hard-edged construction - spaceships, miniature sets, and architectural stuff. These objects were sometimes just 12 inches across yet needed enough detail to fill a movie screen.

Whether it's the experiments on 'MythBusters' or my earlier work in special effects for movies, I've regularly had to do things that were never done before, from designing complex motion-control rigs to figuring out how to animate chocolate.

My advice is keep your lips away from the spinning things.

Don't work for fools. It's not worth it. Getting paid less to work for people you like and believe in is much better for you (and your career) in the long run.

If I haven't had any long term psychological side effects from all the things I've already done on this show, this isn't gonna hurt much more.
