On the Google homepage will be a Google Doodle about Doctor Who. Doctor Who was a British TV series. The Google Doodle will be an interactive one. You have to choose one of the characters of Doctor Who and then you have to solve a labyrinth. After you found all six Google letters you will win. Be careful with crashing in on of those moving objectives. If you do, you will get a time penalty. A very awesome Google Doodle. It takes me almost 5 minutes to solve it!
