I've seen suggestions that somebody make this list, but haven't seen it done yet, so here goes...

Always looking for ways to strike up a conversation about the hobby? Having an intriguing wallpaper on your monitor at work can do the trick.

I'll run some searches and find enough to get us started, but I'm counting on the rest of you to really fill this thing out.

Please add images that you have used as wallpaper to this list. Prefer images that are common screen resolutions: 1024x768, 1280x800, 1280x1024, 1440x900, 1600x1200, 1920x1200. But most importantly it should be very large and clear.

Update: Added bigger images. Did I mention this is my first Geeklist?

Tip: to show a bigger image:
[ ImageID=123456 medium]
Without the space between [ and ImageId at the beginning. Please don't use large or original, they too long to load, people here are clever enough to click through to the image page and get the full size version themselves.
