Subject: [Puptcrit] Shadow screen idea

I was just at Staples (an office supply chain in the U.S.) and was 
looking at the chair matts... the plastic that you put under your 
rolling office chair to avoid damaging the carpeting.  The cheapest 
($20) Rubbermaid one was a transparent plastic with a textured 
surface.  It was approximately 4'x5' square (the protrusion that goes 
under the desk looks like it could be cut off easily).  It is 
obviously very tough, and it was possible to roll it up. I held it up 
to the lights, and it seemed to do a reasonably good job at diffusing 
the light source.

It might be useful as a shadow screen, or perhaps even a rear 
projection screen. It might be especially good for "Black Light 
Shadows" where you use black light in front, and fluorescent "shadow" 
puppets.  (which, of course, aren't really shadow puppets at all, but 
are constructed like them)
