Over at the BBC Doctor Who website you can find this very nice image to download as desktop wallpaper.
An earlier proposed design exists for this image. One originally intended as a quadruple tribute to both the tenth and eleventh Doctors as well as new producer Steven Moffat's personal favourite, the fifth Doctor, and the finest piece of Doctor Who merchandise ever made the Suchard Easter Egg.
Sadly design considerations meant this first image was rejected. The tumbling TARDIS was felt to be awkward from a layout point of view and there was a general feeling that simply too many different elements were present in the picture.
However all is not lost and you can see this rejected image below in all its glory.
