If you're a little bored with your current computer wallpapers and you want to tizz your desktop up a little, there's a great resource available from Desktopography.

It's actually an exhibition of nature-themed computer wallpapers, all free of charge and all readily downloadable.

Each year Desktopography, a non-profit project, has encouraged artists to create images for people to download and install as their desktop background. The only restrictions on their masterpieces is that they need to be based on a nature theme and they need to be easy on the eye.

If you consider how often we sit in front of our computers, finding a desktop that you can enjoy is worth searching for. But, your search is over. With 40 new images in the 2007 collection and 25 and 10 respectively in previous years, you're bound to find a computer wallpaper that suits.
