You're appear to be asking, in a Computer Enthusiasts forum, if there are any pictures on the internet that would make a cool desktop background. Seeing as how there exist ~867 billion terabytes of images on the web, I'm sure you'd have no problem finding one or two you'd like.
Try
Deviant Art's 3D wallpaper section, or
Digital Blasphemy for starters. Also, entering words suchs as "3D Desktop background" into a
Google search query would probably occupy you for days on end.
Desktop images are rather subjective, personal items - each person has his or her own tastes in what they consider to be "cool." It would be rather useless for someone else to tell you what image you should have on your PC's desktop.
Now, if what you are looking for is some sort of shell-replacement, one that significantly changes the way Windows appears, you are more than likely going to have to install some 3rd party software.
