The incredible kinetic sculpture you see here is named Rolling Through the Bay. Artist Scott Weaver started work on the complex sculpture 35 years ago, and continues to modify and expand it to this day. A depiction of San Francisco, the model uses more than 100,000 toothpicks with multiple balls running around city areas to give you “tours” of the city. Scott has spent more than 3000 hours on the project, and the toothpicks come from all over the world. As the artist himself, friends and family go out for holidays, they never forget to return with toothpicks.
