I've been in a grungy mood lately, so I decided to carry that over to my third iPhone background wallpaper. I dug up an ancient photo I took back in the day when I was into 3D- I used to take pictures of all kinds of interesting textures with the idea of building up my own nice library of textures to apply to my 3D models. Anyway, take one rusty metal pic, some cool Photoshop "grunge" brushes, apply some layer modes and voila- iPhone Spade-Skull Background #3.
