Matt Ferguson's 50th Anniversary tribute to the Doctors does a great job of capturing each one's personality and style, from William Hartnell to Matt Smith (You'll also note that the background for each is inspired by the opening credits for that Doctor.) It just feels like a great, dignified summation of a show that has run (more or less) for five decades and been the proving ground for more than a few larger-than-life personalities.
Here's to another fifty years, Doctor!
