At TED 2010 Blaise Aguera y Arcas (Architect at Microsoft Live Labs, architect of Seadragon, and the co-creator of Photosynth) demonstrates augmented-reality in Bing Maps. The demo is amazing and combined typical 3-D maps, augmented with Flickr photos, in-door “street view” images and a video overly on the in-door street view images and integration with Worldwide Telescope.
