When I was taking photos for our preview of King of the Flies Vol. 1: Hallorave by Mezzo & Pirus, I observed that the endpapers might make a nifty desktop background. One request to the art department later, and presto! (Note that this image is Not Safe For Most Workplaces due to partial nudity.)
Just click on the size that matches your monitor resolution and the image will open in a new window; if you're on a PC, right-click the image and select "Set As Background"; if you're on a Mac, control+click and select "Set As Desktop Background." (We don't know what the procedure is for iPhones, but if you have one, you probably do, right?) For lots more wallpaper selections, find recent ones here and older ones here.
