3D games have been doing this in replays for a while now and I’m not sure what ueful applications it would have in entertainment beyond the initial OMG-look-at-that moment, (after all, much of what makes film interesting is the restriction it places on a viewer’s point of view. How many of us ever used mutliple viewing angles on DVDs more than once?) but still, neat-o.

(Click inside the window once the video’s running to make it work, btw).
