Question, I am sorry first off is this is the wrong section but here goes. Lately when I go to the local cineaplex, they have these projectors set up in the hall ways. And there are very light white screens hanging down that are used with the projectors. These projectors show either short commercial movies, or just stills. My question is what kind of screens are they using? I will say one other thing, they have a projector on each side of the screen so both sides are being used at the same time, and it does not go through on the other, as I have checked. I am wondering all this as it looks like the screen is SO light would love to use something like this at home. Thanks in advance for any help!!!
