I had the pleasure of taking Human Anatomy and Physiology a few years ago. The professor was superb, but our school didn't have the resources to afford a cadaver lab.
Pictures and plastic models are OK, but there are times when being able to visualize something like this would greatly help the learning experience.
I agree that visualizing greatly helps the learning experience in science and engineering and that tools like this would be very helpful in the areas of medicine and biology. A cool next step to this would be some sort of "virtual surgery" that could pay attention to what both hands were doing at once.
