My guess is the ridges have to be perpendicular because the audience is
sitting left to right (of the screen).

Wasn't Ron Labbe selling some screen material suitable for 3-D? I remember
he was promoting this at Richmond (NSA 98 convention).

Maybe John Rupkalvis has some leads?

I wonder where Imax gets their screens from? Funny thing about those screens
is that you can see right through them when they are back lit. I was able to
see
this when they had a demo of the Imax system and had a show laser light show
before the main feature. I wonder how does that impact on their reflective
efficiency.

I think someone on this list had posted they got old Imax (or another
theatre)
screen material for almost nothing when the theatre was upgrading their
screens.
Lucky guy (or gal)!
