Wallpaper Slideshow Gnome

To have a simple slideshow as wallpaper, ubuntu and gnome allows to define a list of images in an .xml file. So i build a little bash script that creates an .xml file out of all image files within a directory. This generated .xml file can be used as slideshow by simply adding it as a wallpaper. In gnomes wallpaper dialog.
The script can be downloaded here. http://code.google.com/p/mkbackground/downloads/list

* simply put the file in a directory that contains images
* executed it
* select the generated slideshow.xml as wallpaper
