desktop backgrounds

I was just wondering what people use as their desktop backgrounds.

I achieved a lifelong dream and went and saw Queen (with Adam Lambert) in concert in London 4 years ago. My desktop background is a photo I took about 2mins after they'd finished, and is of the stage with the lights still on and everything. I love the colours and the fact that any icons and files I have on my desktop don't get lost in the background!
