To see mine in it's full setting takes three pics, first is the basic view without doing anything...

Second is the start menu and task bar, which is hidden by default...

And finally, the third is where I keep my "desktop" files...

As you can tell, I run a very clean desktop, and my religious affiliate is blatantly obvious. The "watermark" in the bottom right is because I'm running windows 7 64bit ultimate in test mode so I can use my ps3 controller to play FFVII with an original playstation style controller, and you need to use custom drivers for that, which have no digital signature and 64 bit windows requires driver signing unless in test mode.
Of course, I'll post my ubuntu desktop sometime in the future, and both my server desktops too, but that's for another day when I feel like taking screenshots on them, putting them up and posting on here.
