Scott Weaver's Rolling through the Bay from Learning Studio on Vimeo.

Though we've showcased this magnificent sculpture in the past, here's a new video that reveals a bit more about Scott Weaver's Rolling through the Bay, a munti-toothpicked piece that has pingpong balls rolling through neighborhoods, historical locations, and othersymbols of San Francisco. It took Weaver 35 years to make. The piece, we should point out, is ever evolving.

The sculpture will be on display at the Tinkering Studio until the end of June.
