Scott Weaver's incredible toothpick sculptures

By day, Scott Weaver is a grocery store clerk. When he's not working, he's making elaborate sculptures out of toothpicks and Elmer's Glue. His tool is a nail clipper. His largest work is called "Rolling Through the Bay." It's a 9-foot sculpture of San Francisco. You drop a marble in it at the top, and it will take a rolling tour through Coit Tower, Chinatown, the Golden Gate Bridge, and other landmarks. It took him over 3,000 hours over a 30-year-year period to make it, and it has 105,387 and 1/2 toothpicks.

I saw Scott's work at Maker Faire a few years ago, and it has stuck with me ever since. This video is part of an excellent series called "Coolest Thing I've Ever Made."
