Scott Weaver's "Rolling Through the Bay" has been under construction for over 35 years, and includes over 100,000 toothpicks that are not only sculpturally incredible, they are kinetic as well! As he drops ping-pong balls through different holes in the sculpture, they move through different San Francisco landmarks and neighborhoods, finally exiting in the bottom. Watch the video at the bottom of this post to fully understand the complexity of this enormous toothpick tower. Via Colossal.
