Also note that one's eye muscles focus and react to much faster flicker rates
than does one's perception of flicker.  This is a reason some of the standards
for *minimum* scan rates on computer monitors are quite a bit higher
than rates where flicker seems to visually go away (and a *LOT* faster than
television where in the U.S. the total image is updated at only a 30 Hz
rate (but my computer monitor is running at about 80 Hz)!

This is wandering a bit off of 3D stuff, so maybe we should wander back.....
