A free program for Android, by Dream World HD Live Wallpapers.

The free Water Live Wallpaper HD app is a beautifully designed application that gives you the freedom to change the look of your device into one that is full of beautiful water drops. The app offers you a choice of ten different background styles as well as the speed and density of raindrops and rain. You will also have the option to choose between a soft drizzle or a heavy rainfall. The backgrounds are so realistic that you can almost hear the sound of the water. You can change the settings to suit your needs and use the app for your home screen or lock screen.
