If you would like a wallpaper that will send you chills at night, you should get this Joker wallpaper so that you can get scared out of your wits. Do remember that Joker is actually a fictional villain in Batman but although he already looked a bit creepy in the cartoon series, the way he looked in the movie was really grotesque especially in this computer background wherein he is still seen smiling his chilling smile. The black background that can be seen on this picture fits perfectly well with the rest of his scary looking face and you may never know, it might also make you smile in a weird way.
