It's kinda hard to find wallpapers for my desktop. I like the ones that are large enough to span over 3 monitors (nearly impossible to find, and even then, they would have to be stretched to fit), but with the center monitor being larger than the other 2, it generally doesn't end up looking too great. So I finally gave up that and went with 3 different pics.
Beach pic is one a guy on another forum I frequent took. He gave me the full res to use. Center one is just a coolish one I found. I ran out of different ideas for my last monitor and went with a pic of Zooey Deschanel, lol.
Sorry, I was too lazy to scale it down...
Running Windows 7 Pro. Monitor setup: 19" - 24" - 19" It's quite spacious. I will probably cry if I ever have to use Photoshop or Illustrator on a 17" full screen ever again like I had to in Digital Graphics class last year.
