LSOC WALLPAPER
One size fits all. Wait for the image to load (it's quite large so it might take a few seconds. It may also be too big to fit in your browser window and will appear offset to the right, but don't worry about that).

Once COMPLETELY loaded (when your browser says 'done' at the bottom), right click over the image, and click 'Set as Wallpaper' et voila! Next time you see your desktop, you'll be reminded of the LSOC. Oh and one last thing. Go to your desktop, right click it, select 'Properties' and make sure that your wallpaper is set to 'centre' and NOT 'tile' or 'stretch'.
