And just for side interest, the LCD screen on my expensive 21" Sun
monitor is polarized exactly wrong, such that you simply can't use it
while wearing polarized sunglasses. The Sun engineers who designed it
knew computers, but not optics.

Another aside - aviation instruments are often designed with
circular polarizers so the brightness doesn't change at any
angle when wearing polarized sunglasses.


Thanks -- interesting, and the sensible way to do it.
