The moon on the left moved a lot during the three images this was done with - so it was a big of a botch-job to create that, but I really like it

That's not bizzare, its merely a couple of aliens playing a game of pong with the F ring.

This is enhanced version, clearly showing wath should be the mechanism of fabrication of "density waves" in the F ring:

In fact, image was taken immediately after alignment between Pandora and Prometheus (the two super-exposed spots outside and inside the ring, respectively).
Combined tidal pull from the two moons creates a void in the inner part of the F ring, which then evolve in a spiral structure due to differential rotation.
The other two spiral strucutres visible in the lower portion if this image and more evident other imoages from this sequence (like http://saturn.jpl.nasa.gov/multimedia/imag...iImageID=37522),
are "fossils" from previous alignment events, which should occour every abot 39 rotations of ring-F material (about every 24 days) and should be separated by 9 degree each other.
This is another great example of the incredible gravitational Luna Park offered by Saturn system! I would like to simulate these formations, anyone expert of n-body simulations?

Looks like they shot an F ring movie. Looking forward to the ani-gif or QT movie.
