A toothpick might be the simplest device known to man, unless that man is artist Scott Weaver.

After 35 years and roughly 100,000 little wooden toothpicks, the third-generation San Francisco resident has created an incredibly intricate and interactive replica of The City by the Bay.

Titled "Rolling Through the Bay," Weaver's project chronicles life in his home city with a kinetic tour through San Francisco's sights, monuments, and history. Ping-pong balls roll down winding toothpick tracks, visiting the Golden Gate Bridge, Alcatraz Island, and The Palace of Fine Arts, which contains a heart that, of course, was "left in San Francisco."

"I have used different brands of toothpicks depending on what I am building," Weaver explains on his website. "I also have many friends and family members that collect toothpicks in their travels for me. For example, some of the trees in Golden Gate Park are made from toothpicks from Kenya, Morocco, Spain, West Germany and Italy."

Weaver's masterpiece also features wooden models of a Rice-A-Roni cable car, a dragon for China Town, a psychedelic tribute to the Haight-Ashbury neighborhood, the Painted Ladies (think "Full House” homes) and a miniature of the World Series trophy.

"Rolling Through the Bay" will be on exhibit at San Francisco's Tinkering Studio until June 19.
