Many years ago, there were several experiments with 3D films. Some were on general release, and you were given a pair of 3D glasses with your ticket. We wouldn't have paid £1 for them, never mind ONLY £50. How times have changed.
I'm of a similar vintage. Oue glasses were red and green - were the blue ones the luxury version??
There was a sort of relaunch a few years ago of a clear lens and a darkened one. It relied on a moving background/glasses combination to give the effect. Could never catch on as there aren't that many opportunities to have continually moving backgrounds. It was in colour though.
I will admit to seeing "Spacehunter:Adventures in the forbidden zone" a cheesy movie in 3D at the local fleapit many moons ago. The glasses weren't red and green though, I seem to remember it was something to do with them being polarised at 90 degrees to each other.
no these are not red & green thay are real glass that inter lock with you monitor refresh rate and thus 3d is formed thay will work with other cards not just nvidia cards you should go to there wed site click here once you tryed them you will not look back
