Planetary Snowball Fight!

Not really, but it does make for a nice title. Saturn's rings are a collection of tiny pieces of ice and rock, and the combined gravitational push and pull of Saturn's moons causes this material to clump into beautiful structures, as you can see here and here and here. This is how small, icy moons are made by the way- which is really cool to observe.
