You might not think that looking at a rock on your desktop is the most exciting way to spend an afternoon, but this screensaver isn't quite as dull as it sounds. The rocks in question are actually part of some quite beautiful scenary and provide a nice way to decorate your desktop while your computer is idle.

Although there are only six images (one of which is a garish advert for the developer's site) the screensaver comes with a nice range of options for customizing the look and behaviour of the display. It's nice for a while but we can't imagine anyone other than Barney Rubble wanting to pay to download the extra 20 rock images from the developer.
