There are a few ways to get a moving wallpaper. One way is to download a live wallpaper app from the Google Play Store. Once you have installed the app, you can select the live wallpaper you want and set it as your background. Another way is to download an animated wallpaper from a website like Wallpaper Engine. You can then install the wallpaper and set it as your background in the same way as a live wallpaper.
