Summary: Could this be an illusion?

This is not meant as a joke, a casting of doubt, or in any way as a
cute or 'smart' remark.  It is meant totally as a searching for truth.

I have noticed a tendency for my Mac+ screen to wiggle after a while.
For me, at least, this is an optical illusion.  I sat down and put
put the edge of a piece of paper next to the characters and suddenly 
they didn't wiggle anymore ...

Have you put a straight edge of some kind next to the wiggling lines
to see how much they wiggle?  If it is measureable, then it would have
to be real.  (It might even be easier to fix if it is real ...)

The 'clustering' of the effect would also be explained by an individual
either having or not having a susceptability to this effect.  If it is
an illusion, maybe there is something else that could be done to 
eliminate it?  

(This is all idle speculation on my part.  I am not an authority on the
Mac at all.  I just babysit unix boxes.)

BTW, my neighbors SE has a 'rock steady' display by the paper test.
