From the "just plain cool" department. I love animations of planetary images and I love radar images of asteroids -- so this animation is doubly cool. The only thing I don't like about radar images is that they have a lot of salt-and-pepper noise. So I fiddled with the animation they released, doing a Gaussian blur on each frame to try to reduce the effect of the noise. I think it helps make the rotation more visible, but if you'd like to see the original you can check it out on Photojournal.
