One word: Gobsmacking.
What you see here is one man's work of 35 years - and around 100.000 toothpicks crafted into one sculpture of San Francisco. Scott Weaver spent more than 3000 hours to assemble the toothpicks that his friends and family collected for him from around the world.
It is not the biggest sculpture made out of these tiny wooden sticks but it is probably the only one that comes with the inbuilt kinetic features. Weaver cleverly constructed little tours into the model on which he sends ping pong balls which pass by places and buildings that are all somehow connected to his life and the city. Watch the video! It's magnificient.
