Here's a nifty little animation of Hyperion rotating as Cassini passes by, tossed together by an amateur from images on the raw image website. I don't know enough about the geometry of Cassini's and the moons' motions to know how much of the rotation we see is the moon's rotation on its own axis, and how much is because of Cassini's motion. In any case, I thought it was cool how the close spacing of the images in time allowed this animation to be very smooth-looking.
