I just posted a video that shows the effect of diverging and converging images in post:
The effect is not very interesting when viewed cross-fused or parallel (your eyes will adjust for the small offset), and has a more pronounced effect when viewed in some sort of overlay mode. You'll want to click through and use the drop-down to watch with 3D glasses:
If you view it cross-fused or parallel, look for Berkley moving in and out of the frame in relation to the floating text. That (and, some eye strain) is all you'll see because your eyes will automatically adjust for convergence and divergence in these viewing modes. With glasses, you'll see the entire image shift in and out of the window.
High-end boxes can do this with the turn of a knob in real time, but I don't have access to those so I have to burn them in during render.
