By 3D I mean anaglyph 3d with 3d glasses like the red and blue ones. I've seen some ways to do this but they are at least two years old. I'm using ubuntu gnome 14.04. I'm using nvidia 330m, but by all means post even if the graphics card needs to be more powerful still (I'm getting a better computer soon).

I'd like to be able to do this on gnome, but if it's for unity that's fine. Even better if it's universal for all desktop environments.
