Don't use plexiglass.  It distorts the image and scratches.  Go
to an art supply store and pick up some Rubylithe.  It is a
colored film acetate that you cut with scissors to size.  When
laid flat on your screen it adds zero distortion to the image
and a single sheet is usually perfect for the required light
level.

I generally buy a pack of 25 8.5" x 11" sheets every couple
of years.  Around US$20 IIRC.  One sheet will last for 3 or
4 months if you mistreat it <g>.  The rest I wind up giving
away over the years.  Or trade for a Coke....

Does anyone have a source for a red plexiglass laptop screen cover? I'd like
it precut to size. Thanks!
