The Chop Shop has some side projects as well. Here is a little something from wanderingspace.net for your iPhone. 19 of the major bodies of the solar system to swap out that tired of image of Earth that came with the phone when you bought it. You will see familiar bodies like Earth, Mars, Jupiter… but also included are such exotic places as Io, Europa and Triton. If you are unfamiliar with the major moons of our celestial neighborhood, be sure to check these out. You may be surprised.
