Wallpaper changer app?

["Dennis J. Tuchler" <dtuchler earthlink net>]

Is there an application for Gnome's desktop that displays a graphic on the background 
and changes it for another graphic (e.g. in a particular directory) each n minutes?

There is such a utility included with KDE, but I'd rather use Gnome.

Thanks
