Courtesy of the Open University, we have three QuickTime Virtual Reality Models. To view these models, you will need the QuickTime 3.0 plugin for your browser. This comes as a part of the general Quicktime 3.0 download on the Mac, and I assume the situation is similar for the PC.
For those of you more inclined towards VRML, we also have a VRML model of The 1903 Wright Flyer.
