Stewart Screens
Stewart, a big (and expensive) name in home theater screen technology, was showing off some interesting uses of its StarGlass technology. StarGlass is a rear projection technology that allows you to project an image onto screen fabric sandwiched between glass panes and maintain a good amount of brightness and contrast even in situations with a lot of ambient light. Essentially, StarGlass projections look very similar to viewing a plasma or LCD direct view display with a glossy screen.
Here Stewart is showing off the StarGlass system integrated into a bar. The projectors are located on the underside of the bar. The screens are sealed and waterproof.
In this situation, StarGlass is integrated into the floor of the second level of Stewart's booth. The screen can support the weight of a certain Editor in Chief of an online publication.

I don't know much about projectors but, is it too difficult to manufacture a native 2.35:1 projector? This way only 16:9 and 4:3 movies would have black bars on each side. Imagine, a true 2538x1080 image... :-)Fluppeteer - Monday, September 10, 2007 - link
Well, there are 4K projectors, if you've got the input and the money. (Or you can just run two SXGA projectors on their sides, overlapping.)This is the first I've heard of the anamorphic business. I'm confused: given that there's no more data available to add pixels, why digitally scale up (removing some high frequency information in the process, unless there's something exceptionally clever going on) to fill the 1080 pixels of the image, then stick an additional anamorphic (expensive and complicated, and probably not quite as high quality as a "normal" lens) lens in front of the existing optical elements? What does this gain you that sticking a bog standard wide angle lens on the front of the projector (and putting a couple of bits of cardboard over the borders if your projector has a poor black point) doesn't?
It just sounds like a really complicated and expensive way of making the image worse. Am I missing something?

The last (bottom-most) picture on Page 7 appears to be upside down.BigToque - Friday, September 7, 2007 - link
The projector could also be upside down and attached to a ceiling mount.
