Several of these are ones I've posted before. A new one is an animation based on Huygens video, with the POV now able to move around:

Apparently they've moved stuff around on the site a little bit lately. I had only one QuickTime that didn't load right. Otherwise, this is some of the smoothest video I've seen -- but WARNING: some HUGE downloads!
Many of the videos showing approaches to Saturn's moons start off with a deep zoom, followed by a pan. Cassini is actually thousands of miles away, but the visual effect is as if the probe (and POV) is about to crash into the surface -- then suddenly it starts to turn aside. A little disconcerting in places.:)
