Behind the scenes
In celebration of the 50th anniversary of Doctor Who, Google released a Doctor Who game as their logo "doodle", codenamed the "Whodle." It was one of the most complex doodles that Google had ever done, with 5 levels where the player worked to retrieve the six letters to the Google logo while avoiding the Doctor's foes. Every incarnation of the Doctor was playable (if the player was killed by a baddie he would regenerate into the next Doctor, with infinite lives), and the Daleks, Cybermen, and Weeping Angels featured as villains.
