This beautiful pastel impressionist design was created by graphic artist Josh Joseph, who works professionally as DBLJ Design. Unfortunately, Mr. Joseph seems to have disappeared from the Internet since May 2009 and could not be contacted for further comment on his Apple oriented design work. © 2007 Josh Joseph.
It’s hard to get more simple, perhaps hard to get more beautiful than this stark grayscale image from Brazilian Flickr artist Guileite. He calls it an Apple TV wallpaper, which may account for the original’s 1280×800 size. Used under a Creative Commons license.
