Just thought I'd give everyone a heads up on this auction in case anyone is wanting to test a silver fabric that is simple and cheap. Looks like it may have some potential. I'd probably buy it if I was still using my digital projector (I mostly use my CRT, but even still I'm tempted to try the fabric with it). :D
It's a tad small (you could probably get about 86" diagonal in 4:3), but is really cheap and could be used as a cheap test to find out if it's worth buying a larger version.
Ebay auction number (just copy and paste on Ebay search): 5618165837
