My usual setup is three desktops, all with background images that rotate every 5 minutes from a folder of 300+ image. I have no icons on the desktop and an autohiding bottom taskbar.
So any screenshot is kinda false and boring.
Instead I dropped my wallpaper folder into imgur, so you can look through all of them. Almost all of them are video game related.
Also, everything is SFW and nothing is *too* big of a spoiler (unless, maybe, you want to go through Spec Ops: The Line completely blind (which is recommended)).
