P3D Interesting visual phenomenon discovered.

["Greg Wageman" <gjw@xxxxxxxxxx>]

Here I am sitting at my computer with a pair of red/blue glasses.  I was
looking at an anaglyph that a list member e-mailed me.  Most of my
computer screen is occupied by Microsloth's "Outlook Express" window, so
there's a lot of white.

Simply by coincidence, after viewing the anaglyph for maybe 10-15
seconds, I closed one of my eyes, and to my great surprise noticed a
VERY obvious tint to the once-white screen.  I was amazed to discover
that just 10-15 seconds with these glasses over my eyes caused a very
distinct "after-image" of the complimentary color!  I.e. my left eye
which had been looking through the red lens now had an obvious cyan
color shift, and my right eye a red shift.

Try this!  Only 10-15 seconds of looking at a white screen through
red/blue glasses should produce the effect.  Interestingly, with both
eyes open I don't notice anything unusual, but put a hand in front of
one eye and the color bias is instantly obvious.  It seems to linger
much longer than the time it takes to create it in the first place, too.

I also noticed that my pupils were apparently "hunting", as the apparent
brightness of the screen was shifting.  This is another reason I dislike
anaglyph.
