Now as I understand it, color-blind people tend to have a better
sense of depth discrimination. (i.e. in WW2 they were used
to detect camouflage, I do not know if they are used this
way in Desert Storm). Questions:

1. Is this something genetic to color-blind individuals?

2. Is it something that could be trained, and then exploited
   by scientific visualization packages?

3. What does it mean to have a heighted sense of depth perspective,
   Does it help in standard computer graphic output (line, shaded
   polygon, texture maped) diagrams, or is it only exploitable
   when a higher level of visual realizim is avialable?

4. How would you switch from color information to perspective
   information for a color blind person?

5. Should TekCMS do a color test on the user :-)
