Cassini nabbed a nice set of views of Epimetheus yesterday. Epimetheus is one of Saturn's smaller moons, orbiting between the main ring system and the larger round moons. Epimetheus is nearly co-orbital with Janus, which has four times Epimetheus' mass; the two dance past each other once every four years.
Epimetheus may look similar to Phobos, but it often looks dissimilar to its own self. Here's a nice montage of five images of Epimetheus, four from Cassini and one from Voyager.
