What’s Your Desktop Wallpaper?

I like to post the wallpaper I have on my computer from time to time. I find it interesting, as, to an extent, it communicates something about me. On my computer, I have 3 desktops, so I currently have 3 wallpapers:

I obtained all three of these in high resolution format from Wallpapers HD Lite, an application from the Mac App Store. I love them. Why? Blue. It is my favorite color. The first one of the Golden Gate Bridge is really cool, being that I am from California. The second looks like it is from Tahiti, and my wife really wants to go there. The third, is that Chicago? Well, I like the blue lights in the dark setting. Pretty.
