In preparation for Christmas and the premiere of this year's remaining Doctor Who specials, the BBC's official Doctor Who website launched their online advent calendar for 2009 last Tuesday. The advent calendar will feature many exclusive treats over the next eighteen days and door number six on the calendar is now available to open due to the fact that today is the seventh of December. Behind today's door, there are several new wallpapers for this year's final Doctor Who specials, The End of Time, and they can be viewed here. Content from behind the calendar's previous six doors can be found here, here, here, here, here and here in previous posts. This year's eighth door on the calendar will be available to open sometime tomorrow afternoon and details regarding the next special advent treat will be posted here on this site soon. What do you think of these wallpapers?
