Animated wallpaper - can Windows do that ? :P

Since I've seen animated wallpaper on YouTube (here) I've wanted to have it. It's done with amazingly small program - xwinwrap. I won't repeat stuff that's already on the net so here is How to.

Unfortunately this little eye-candy consumes a lot of resources (specially using mplayer), just like snow effect in beryl. On the other hand it is certainly nice to have matrix or some movie (with some slow-moving stuff) on wallpaper.

Oh, and there is one drawback - xwinwrap covers your desktop icons. You can use them, but if you want to see your desktop icons xwinwrap has to be transparent. :(
