This photography project in Chicago seems pretty interesting. I do hope that they fill in the glaring south and southwest side holes in the map. Try 63rd and Kedzie. It has always been a particularly strange and busy intersection, though not as loopy as Wilson and Broadway.
And get over to the long forgotten steel graveyards on the south east side. I hope they put a full photo set up when all is said and done. A virtual art gallery might work perfectly for such a project.
