SF graffiti doc Piece By Piece will be showing tonight at Ocularis, a not-for-profit film organization based out of the Galapagos art space in Williamsburg.

If you like documentaries (we do) and defacement of property (ditto!) you will dig this flick, documenting over 20 years of San Francisco graf pieced together from hundreds of hours of interview and archival footage collected over the past three years.
