Like Google Street View with a flux capacitor

Dan sends us word of his new project, OldSF.org, which overlays 13,000 images from the San Francisco Public Library’s Historical Photograph Collection with their locations on a map of San Francisco. The result? A time-travelling google street view.

Spend a couple of hours on it today and impress your friends this weekend at Dolores Park with a snide “man, this place was cooler when it was a refugee camp.”
