Yale Stewart, creator of the popular "Justice-League-as-kids" fan webcomic JL8, has created some wallpaper that he's selling to benefit victims of Monday's bombing at the Boston Marathon. There are three versions: the one above, a reversed image with the Flash running toward the left, and a left-running one sized especially for Facebook covers. A $1 donation (or more, if you like) gets you all three in a zipped file. Stewart will divide all proceeds equally between Boston Children's Hospital and Red Cross of Boston.
