Heres a bunch of free cool HD computer desktop wallpapers i found while looking around. Check out the third one now thats cool and pretty nice quality. My apologies but i dont stick to just one resolution because its not fair for people with different sized screens, widescreen for example. Some of the most saught after graphics are ofcourse music wallpapers because everyone likes music and the backgrounds are usually quite amazingly designed pieces of work involving alot of colour and textures.
