This is what I believe James Cameron should have done with that Na'vi Boobs.

I wish James Cameron would have made Neytiri Boobs bigger. He did this interview on Playboy and made it sound like there was going to be some boob jiggling physics action in the Avatar movie, but there was absolutely no boob physics action. The motion capture did everything except animate her breasts. To make up for what he did not provide us 3D Stereoscopic boob fans. I have made my own version.
