I bought a pair of 3D Glasses, and while looking to see those cool images/movies, I've discovered a plugin for Compiz, which enables Anaglyph for a window or for the entire screen. The effect it's kind of cool, but it's sad that they created this in 2008, and since then there isn't any change.... Perhaps Ubuntu will come in the future with it's own 3D mode.. who knows. .? Anyway, this is just for fun, because you can't actually work with this option on and with your cyan-red glasses.... it's tiring for eyes.
