Could you please send me that picture, that's absolutely beautiful.
It's part of the windows 7 install package. If you are in GB, go to your globalization folder in your system files and there's a whole bunch of wallpapers in there for different localizations.
This particular one is in America I think.
It changes automatically ever 30 minutes because of the wallpaper slideshow that Windows 7 has. One of my more favorite features.
