This might just qualify as the most wonderful thing I've seen all day: A customizable Super Mario live wallpaper for Android devices. It works on Android 2.1 (and up) and looks crazy fun. Check out the video and you'll see.
You can download the wallpaper over at XDA-developers, but I'd suggest being kind and tossing the developer behind this gem a small donation if you can. [XDA-Developers via Android Central via Engadget]
