However, I was much more impressed by a product from the German company Woehburk, especially their Cristalline, glass projection screen. I thought that it showed a brighter image than the other products, with better contrast and color. Perhaps I was charmed by the small scale, as I wanted to design some kind of suspended 'chandelier' type array of small glass projection screens. I really like the way that the image is only visible from one side, which makes it appear quite magically, if you're just passing by...

In this video I compare three different Woehburk screens and then compare my favorite with an opaque rear projection sample from 3M's Vicuity range.
