Can somebody enlighten me what an animated background exactly means? Is it like a video/gif running on your background endlessly in a loop? Or does this mean simply a wallpaper slideshow, where the wallpaper changes every X minutes/hours (or possibly based on the daytime, so a different one for the morning/noon/evening/night)? If the latter is correct, am I the only one who sees the term "animated background" as super-confusing here?
