It has taken 3,000 hours and 34 years to make – but the results are incredible. Artist Scott Weaver has created a huge but incredibly detailed model of San Francisco using 100,000 toothpicks. The work entitled Rolling Through the Bay also doubles as a marble run. Ping pong balls dropped on several ramps at the top of the model follow several “tours” through the city. They pass matchstick replicas of sights such as Alcatraz, Fisherman's Wharf, the Golden Gate Bridge and the city's trademark terraced houses on steep hills.
