I have seen a lot of live wallpapers and, truth be told, I'm generally not that impressed most of the time. Every once in a while, though, one comes along that is just so nice that I want to share it with everyone. This is one of those times.
Photile Live Wallpaper creates a LWP from any existing image. It adds a level of complexity to the images, while not overdoing it (a difficult task, I might add).
