Graffiti Archaeology is the study of graffiti-covered walls as they change over time.  The grafarc.org project is a timelapse collage, made of photos of graffiti taken at the same

location by many different photographers over a span of several years. Most of the photos are from San Francisco, over a timespan from the late 1990’s to the present.

Using the grafarc explorer, the user can visit some classic graffiti spots, see what they looked like in the past, and explore how they have changed over the years. One of the part I like the most is the timeline bar. Something that reminds me so much of the timeline I developed for the Biosphera project. This one is nicer though.
