Desktop background moving pictures

I have been thinking about a desktop background that rotates images that 
help me think during my work. But I have never really found software to 
do this. Oddly enough, just moments ago I got a message from a friend 
who purchased software to do this exact thing. However, its only for 
windows.

If you look at the video, what I like is the rotating graphics.

Does anyone know of ANY software that will work similar to this?

Before someone respond with "just rotate the desktop background", I 
wrote a little program with php to do just this but, its not exactly the 
same. Its ok but not exactly the overall feel I was looking for.
