I have a CD called Visual Man, which gives you an interface to images
of some guy who got cut into 1800 slices and photographed. It runs
under Windows, I don't know how much it costs, but the phone number is
305-572-4848.
The images are not super clear, in my opinion, but that could have been
partly the monitor I was using and I will try it somewhere else before
passing final judgement.
