Imax has been here for a while, but its only now the technology I believe is becoming cheap enough to do full length films in it.
70mm film, I can guess isn't cheap to produce, or store.
Didn't get to see it in the end though, because my mate took too long to pick me up, so got there like 10 minutes late, so it was too late to go in
On that note though, saw The Golden Compass instead, and actually, thats a very good film.
I may have to get the books.
When video cards that can run Crysis well start coming out, you can actually get shutter glasses for PC's you know, and most games do support the 3D feature, built into the Nvidia 3D drivers that you can download.
Haven't seen it been done in a while with new games, but I've seen some Quake 3 3D shots for example.
The video card has to be able to render 2 different camera positions, and its best for your monitor to support at least 100hz I believe for a no-flicker effect.
