Papervision3D Proximity Grid Example
Here is a little experiment that I created on the plane home from Switzerland. I am creating a grid of planes and then I'm using proximity to determine which planes align. If the mouse is a certain distance away it goes back into space at random positions and angles. I'm using Tweener to do the animation. Enjoy it!
