    Not 100% sure but I think they are rear-projection panels.

    I have seen them in shop windows before - some sort of special "clear" screen surface on the window to capture the light from a projector behind, don't know the proper name of them though.

    Fresnel prism screen. I've just put a 10ft one into a boardroom. Modern ones don't suffer so badly with limited viewing angles, and you can get a lot of light out of them, so good for bright environments.

    As the others have suggested your looking at a Daylight projection screen - there are a few types around; the more expensive units are completely clear when your not projecting an image onto them and the lower cost units are grey.

    There are also 'applied' films you can put onto any clear substrate - though these are more costly as they try to give you better definition.

    You use a 2500 ansi+ projector firing at the rear of the 'screen' at an angle that's offset to the viewer - so the viewer can see a 'bright' image without it being destroyed by reflected or incidental light.

    See http://www.holopro.com/ - we've used a few variations on this idea but these are probably the best.

    Best regards

    Joe

    PS Not ideal for 'Home Theatre' applications!!!

    Joe, the guys from Paradigm told me Robbie Williams has one as a HC. The clowns he had install it put their head through 3 mirrors apparently!

    There's an idea! You could get the rear projection rig in the loft! It needs about 1.7m of space behind for a 10ft screen, this one was a Sanyo PLV-WF10, 4000 lumens, 1366x768. It's pretty sexy actually.
