Using Photosynth as a tour guide

In case you still haven't seen Photosynth:

Our software takes a large collection of photos of a place or an object, analyzes them for similarities, and then displays the photos in a reconstructed three-dimensional space, showing you how each one relates to the next.

Note that the software actually identifies the positions of the cameras that took the pictures in the collection.

So in fact, you can use this approach as a tour guide, taking you to places from which many pictures were taken (i.e., the positions of the cameras).

Imagine for example walking around a city while a device points you to nearby places from which many pictures were taken and orienting you in the direction of the often photographed scene.

Such a device could take into account context (e.g., time of day, season, purpose of the photograph, etc.).
