Yes. It's actually very similar to how the Android app Muzei works. The app sets a blurred version of a famous painting or artwork as your wallpaper, and you can access the original with a gesture of some sort (I don't remember exactly what). Something on the desktop, with the ability to use your own images, of course, would be fun and not difficult to make.
