My PC used to have the Astra VXR background which you can download from the Vaux VXR site, however as I have been taking pics of my new baby, I decided to make my own version.
Here it is. http://www.iosys.org.uk/images/vxr_background.jpg
It's 1280 wide, and is a link above due to the size (The filesize is small, the pic size is big)
If you want a copy of it, Right Click and select 'Save as Background'
