One man, 100,000 toothpicks, and 35 years

Scott Weaver is an artist. He spent 35 years and used more than 100,000 toothpicks to create a kinetic sculpture named "Rolling Thru The Bay", which depicts the street scenes of San Francisco, USA. More uniquely, the toothpicks he used to make the sculpture were collected by his family and friends from all over the world. With such dedication, craftsmanship, and persistence, how could his works not be moving?
