So you like the look of this one do you? I suppose you what to know how to get it on the desktop now. Getting the wallpaper onto your desktop background can be done in a number of ways. One way is to right click the desktop background below and then choose 'save target as...' (IE & Opera) or 'save link as...' (Firefox). Don't forget where you saved it though! Then go to wherever you set the background for you particular computer / operating system and select the image.
Another way is when the full screen wallpaper has loaded, right click it and choose 'save image as...' or 'set as Desktop Background' or 'Set as Background'. It'll come to you when the time is right. I've never felt so sure of anything. My guess is you already know. I'll shut up now.
