When tweaking my computer, I always look for some good graphics to set the tone for the desktop. I thought I should pass a few of the places I like to go to find them your way…
First off, we have the JPL site. This week, they are featuring the Cassini images; every week, they have the best of Space image wallpaper, at all resolutions. Then there is the Minds Eye site, worth your time even if you skip the Wallpaper. And for the really good stuff, be sure to check in with the Hubble Site!
