Billed as being wallpapers for Twitter, there is a nice collection of images that you can use as wallpaper for your desktop or web site at the NASA JPL Free Twitter Wallpaper Page. The only caveat is that each image is tagged with a little blue bird in a space suit. This post’s illustration is a full sized reproduction of the section of a Cassini image of Saturn that contains the blue bird astronaut.
