National Geographic is one of my favourite magazines, and a big part of the title's appeal has always been its photography. Whether it's pictures of wild animals in action or shots of remote tribes going about their business, you're always guaranteed to find something remarkable to look at within the pages of the National Geographic magazine.
Now you can enjoy some of these incredible shots on your desktop thanks to this rotating screensaver, which boasts a collection of interesting images from the world of science and nature. Unfortunately, the images are of a low resolution, meaning that you can't really enjoy them on a large format display. However, at a resolution of 800x600 the pictures look OK.
