As an anatomist, first, and a computer-junkie, second, I would love to tackle 
a problem such as this. Here are the caveats as I see them: 
1. Time/materials expense. Although I, and likely a large number of labs, 
possess the tools to complete such a job, the money needed for this 
project would be required UP FRONT.  I'm fairly sure that a good job cannot be 
done in one's spare time with their own funds, thus backing of SOME kind is 
necessary.  I know a number of publishers are sometimes willing to invest in 
such projects. The problem, as always, is having enough data to convince them 
their investment will pay off. 
2. I envision a 3D display that can be rotated, sliced in any plane, 
interrogated by mouse pointer, etc. These are fairly complex tasks that will 
require high-end computers for non-frustating execution speeds. The user 
may require AT LEAST a 486-33 MHz, or a MAC IIfx, or a UNIX box.  In my 
experience these requirements always raise the price of the product and 
decrease the potential market.  The point here is that the product must be in 
a form that would be of value to the widest audience.  That means low cost and 
machine-independence.  

Any other thoughts on developing such a project?
