A shamrock or four-leaf clover live wallpaper for the Luck of the Irish! This shamrock is beautifully modeled. It looks like a real shamrock on your phone or tablet's screen background, slowly rotating (speed is selectable).
To install this - like any live wallpaper - long-press in your phone's background and select Wallpaper. On the pop-up menu select Live Wallpaper and then pick "Four Leaf Clover" from that list. After you have set your settings the way you like them, touch "Set Wallpaper" to make it go.
