As a gamer, I had to post this in it's own thread.
Super Mario sidescrolls way through your Android live wallpaper
This quite possibly is the greatest thing we've ever seen before breakfast (at least since Zombies crossed our desk). That's right, it's Super Mario, scrolling his way on through your Android 2.1 (and up) live wallpaper. He plays through a couple of levels, and you can tweak the settings to show the paths that Mario is thinking about taking. It's all brought to you by pikipirs at XDA Developers, so drop a dime or two in the collection plate if you feel like it. Download at the source link, and check out some video after the break.
