The BBC recently unveiled it's new (but not necessarily improved) Dr. Who logo.
The logo is obviously designed to replicate the Tardis and the title and logo have both been given the new bluey/ purpley hue.
I guess the BBC are going all out to start from scratch with Matt Smith, including changing little things that have been synonymous with the last two (Christopher Eccleston and David Tennant).
We'll see if it all pays off next year!
