One of the cool things is that the picture of Titan obscured by the rings show that they are not all pristine white - they have some seriously dark streaks too. Incidentally, solar eclipses by Saturn are interesting. They would appear to be far more common in this system than in the Earth-Luna system since Saturn is much bigger in the sky, and the sun much smaller. But while the moons are fairly close to the equatorial plane of Saturn, Saturn has an axial tilt of 27 degrees. So hence eclipses only tend to happen around the equinoxes, every 15 years. But then Titan gets 6 hour eclipses in intervals of approximately 16 days. This might cause stormy weather on Titan: http://adsabs.harvard.edu/abs/2001DPS....33.5508M "It was a dark and stormy eclipse; the methane rain fell in torrents — except at occasional intervals, when it was checked by a violent gust of nitrogen wind which swept up the flyways (for it is in Nyhavn that our scene lies), rattling along the domes, and fiercely agitating the scanty glow of the floodlights that struggled against the darkness."
