This unmanipulated photograph (0630) was shot on 17 January 2006 at a memorial to Martin Luther King, Jr (in San Francisco).
This is a Luxagraphic shot of light coming through a series of thick glass panels which were etched with quotes from Dr King.
I tried flipping this one around and played with some various crops, but finally just gave up and posted the image as captured (though I can make no assurances that the camera was itself in any particular orientation).
