After thinking long and hard about why we should be more depressed today than on any other Monday, we think the answer may have less to do with this formula than with the fact that we've been staring at the same damn picture on our desktop since 2004. If you find yourself in a similar rut, we recommend treating yourself to a new view from this quality collection of beautifully designed desktop-sized photomontages and glamour shots. They don't call them "The most beautiful wallpapers in the world" for nothing.
