Ever  tried to do panorama pictures with your digicam? Its not that easy to use, and hard to do real big panoramas. A tool that makes the shooting and generating of  complete 3D Views easy: Photosynth. Photosynth builds a 3D Point cloud of a photographed object. Take a look at http://photosynth.net/ . An explanation of how to use PhotoSynth can be found at http://blip.tv/file/1190926/. Take a look. Its a really cool technology.
