	The LCD panel idea has always appealed to me, seems like a cheap(er) way to 
do projection, plus it allows use of really bright overhead projectors 
instead of being stuck with whatever's in an LCD projector. Where did you get 
yours? Ebay?
	I also recall seeing a page that discussed using LCD panels from laptops (I 
think), with frensel lenses. They made this somewhat large wood box they 
mounted everything in, took the "default" backlighting off the LCD panel, and 
used some sort of bright bulb behind the panel. Looked like a very slick and 
potentially high-quality method.
