In the early '10s, I was into producing 3D photography . I was living abroad, but would soon be returning to my hometown of San Francisco.
I was excited about the history, and discovered that there were a whole bunch of stereograms taken of the aftermath of the 1906 San Francisco Earthquake & Fire. It's an event people vaguely talk about without realizing the extent of the destruction.
The stereograms are hard to see online (or were), and so I edited them into wiggles and put them on tumblr with a sweet domain so people could see them!
