This can easily be used as a sort of poor man's 'desktop widget'.

The method works by downloading some info from the net at regular intervals and then embedding that info into a chosen part of the used theme. In this case, it was the lock screen graphic but it could just as well be one of the desktop wallpapers.

E.g. a downscaled last fm stats image could be embedded into one corner of one of the desktop wallpapers on top of a transparent black rectangle so that it visually would resemble a traditional desktop widget. And voila, you have your own 'desktop widget' which automatically updates it information at a chosen interval right on your desktop.
