One man, 100,000 toothpicks, and 35 years: An incredible kinetic sculpture of San Francisco

Thirty five years ago artist Scott Weaver began work on this insanely complex kinetic sculpture, Rolling through the Bay, yet he continues to modify and expand it even today. The elaborate sculpture is comprised of multiple “tours” that move pingpong balls through neighborhoods, historical locations, and iconic symbols of San Francisco, all recreated with a little glue, some toothpicks, and an incredible amount of ingenuity. He admits in the video that there are several toothpick sculptures even larger than his, but none has the unique kinetic components he’s constructed. Via his website Weaver estimates he’s spent over 3,000 hours on the project, and used over 100,000 toothpicks that have been sourced from around the world:

I have used different brands of toothpicks depending on what I am building. I also have many friends and family members that collect toothpicks in their travels for me. For example, some of the trees in Golden Gate Park are made from toothpicks from Kenya, Morocco, Spain, West Germany and Italy. The heart inside the Palace of Fine Arts is made out of toothpicks people threw at our wedding.

This really is a spectacular work of art!
