The desktopography project arrived in 2005 as a place to download nature / topological themed wallpapers with edits from selected designers. Designers spend about 90% of their waking life in front of a computer so the most appealing genre for a wallpaper would be one that has beautiful design mixed with the all important aspect of being outdoors.
If you love to collect wallpapers, you will surely love Desktopography.net. Enjoy.
