The Graffiti Archaelogy project uses a Flash interface to let visitors navigate to different heavily tagged spots (links at left), then see the work at various stages (links at bottom).  Using the M & N keys to cruise back and forth in time, I’m reminded of watching time lapses of plant life exploding on a surface, dying, and being reborn.  Yesterday Adobe hosted a visit from project founder Cassidy Curtis, but I had to bail in order to avoid guys driving by the building at 180mph.  Fortunately Archaeology.org has the whole backstory on the crew & project.

Elsewhere you can find a Google-powered map that tracks Seattle-area graffiti tagging.  The NYT talks about the way that mapping services are enabling people to plot all kinds of info, from hydrofoils around the world to yarn stores in Illinois.  (No progress yet in getting yarn graffiti pioneers Knitta Please to my hometown, I see.)
