Images: Microsoft maps in 3D

The Tribune Tower is in focus, with the Sears Tower and other Chicago skyscrapers in the background. Unlike Google Earth, Microsoft Virtual Earth does not label its 3D objects. You have to know what the real-life building looks like in order to find it by browsing the 3D map. Otherwise, you must search for an object directly by name in order to find its three-dimensional counterpart.
