I tried out the paper test as well. I thought I saw a wiggle in the
other direction at all times. (ie, when the paper was vertical, I said,
oh horizontal wiggles, when the paper was hoizontal, oh vertical wiggles)
I came to the conclusion that maybe what it really is is a variation in
screen intensity. Some additional observations:
- It is much more pronounced in the upper left corner, not so much so
in the lower right, and on mine I cant see it anyplace else.
- If you want to see something REALLY interesting, go into some sort of
editor with a "select all" option. Place paper vertically on the
right side, punch "select all" and you'll notice the screen move in
about 1/4 of an inch.
- I never notice it and it never bothers me at all except when everyone
here keeps bringing it up. I probably wouldn't have noticed it at all
except that someone brought it up. It does not bother me, I do not hate it.
- The effect is much more pronounced under florecent lights.
(of course it is, everyone blames everything on them.)
Someone made some comments about eating and looking at a Mac screen.
This is an effect that can also be seen at the Exploitorium in SF.
They have a light called "The Bronx Cheer Blub" which is one of those
flickering candle type lights. If you stand away from it and give
it a rasberry at the right "speed" then the flicker will stand still.
