The International Year of Astronomy has inspired many interesting projects.  Perhaps none are as visually compelling as Experience the Planets.  This growing site presents artists renditions of what it would look like to see our neighbors in the solar system up close and personal.  And, yes, for those of you who do not have pictures as cute as The Frogger being buzzed by a hippopotamus on your computer, there are wallpapers available.

The image below (Waters of Europa by Josef Barton) shows an artist's rendition of what it might be like to explore the oceans beneath the icy crust of Jupiter's moon Europa in a submersible vehicle.
