I use a program called 'Desktop Drapes' to accomplish an effect similar
to this. It's installable from USC (just search for 'drapes').

However, be warned...the program is a bit buggy. For instance, it
doesn't automatically start like it's supposed to when it's simply added
to the 'startup applications'. It needs a time delay to function
appropriately. To get around this, I simply made a small script to
launch it with a time delay. to do likewise, just copy/paste this:
        #!/bin/bash
        sleep 10
        drapes &
into a text editor and save it someplace as 'startdrapes.sh' or whatever
you wish (i put it under ~/.config/drapes/), then add THAT to the
startup applications.

Drapes also can't handle very large volumes of wallpapers. so if, for
example, you have 800 wallpapers that you want to rotate between...you
might be out of luck. However, for any numbers below 100 you'll probably
be fine.

hope that helps!
