November 23, 2013: Happy Doctor Who Day to all of you whovians out there. I went with the eleventh doctor here, because the twelfth hasn’t really gotten rolling yet, and Matt Smith has amazing hair. This is a special Doctor Who Day; the show premiered fifty years ago today, back in 1963. It’s also Espresso Day, so the Doctor is enjoying a wee cup with pinky extended. And for you number nerds, it’s Fibonacci Day! I used a spiral here in the doodle, although it’s miles away from the golden spiral of the Fibonacci numbers.
