Came across this interesting video....'Blaise Aguera y Arcas demos new augmented-reality mapping technology from Microsoft.' Flickr photos are layered onto the 3D street views provided by Bing, with some very spectacular results. Could have some useful applications in education.
I discovered that it currently only works in certain locations that allow street level navigation. Once the Silverlight is installed, try the working examples of this augmentation on Bing maps for San Fransisco etc first.
