Hey there, I'm the founder of a small travel app (www.r3d.city) that is essentially a virtual geocaching/treasure hunt platform. We're just about to come out of beta, and one of the new features is seeded historical photos; e.g. heritage sites in the 1920s. We're putting a lot of work into geotagging these photos directly onto the capture location, you might find it interesting. The idea is that as you walk around some historical location, you can view images of that location from N years ago, from the exact point of view (or near enough) where that photo was taken.
