Viewed every day by millions of people across the globe, Bliss is possibly the most viewed picture of all time.
In case you've never seen a computer before, it's a rendered image of a landscape (actually taken from a real photograph of a range of hills in Napa County, California) that is used as the default desktop wallpaper for Windows XP.
If you're a fan of the Windows operating system and can't bear to be away from it for too long, then this mobile wallpaper version of it could be just for you. It's a small-scale reproduction of the original in the form of an animated GIF, allowing you to watch the clouds float along your screen.
OK, so the animation is a little jerky and crude, but this wallpaper offers a good way to pretend your phone is a Windows computer.
