Shutter Live Wallpaper.
As the name suggests is that you can set your phone screen into a shutter when your finger on the screen to slide up and down,
the shutters will open and closed. You can also put your finger on the bottom of the phone screen blinds pulled up.
You can choose the pre-defined window background and shutters color.
Of course, if you have a better picture of the background, you can set it or just take a photo using your camera.
