Today is the seventh of December and door seven is therefore now available to open on the BBC's official Doctor Who advent calendar. Behind the door are four downloadable wallpapers for your computer. Each wallpaper is for The Next Doctor and they can all be downloaded here however please be aware that the first and fourth wallpapers feature images that could be classed as spoilers. I have also uploaded these wallpapers elsewhere online so that anyone living outside the United Kingdom can access them. You can view them in numerical order here, here, here and here. What do you think of these wallpapers? Are you using them on your desktop?
