If you’re a visual person, and you haven’t yet experienced a spherical panorama, you’re in for a treat. It's also called Quicktime VR or QTVR.
A spherical panorama is a photographic representation of the full 360-degree field of vision. Using a special camera apparatus and a photo-stitching technique, an array of photos taken from a single point of observation are seamlessly mapped across the surface of a sphere or cube surrounding the viewer.
The photo above is really just a flattened cylindrical panorama, because it's just as hard to convey a spherical panorama in one illustration as it is to show a map of the globe on a flat piece of paper.
Using a special plugin from QuickTime (resident on a Mac, and downloadable for other computers), you can control your direction of view, and in some cases, you can zoom closer to any given region of the picture.
A good place to start is the website “spherical panoramas” Link.
