Animated wallpaper is a cross between a screensaver and desktop wallpaper. Like a normal wallpaper, an animated wallpaper serves as the background on your desktop, which is visible to you only when your workspace is empty, i.e. no program windows block it from view. The only difference with desktop wallpaper is that an animated wallpaper, as the name implies, is animated, much like an animated screensaver but, unlike screensavers, keeping the user interface of the operating system available at all times. Whereas "regular" wallpaper is a static image, an animated wallpaper can feature animated elements. Due to its lively nature, animated wallpaper is sometimes also referred to as live wallpaper.
