You all can stop making Dr. Who cakes now. It's been done to perfection. Behold the world's greatest TARDIS cake. It has realistic molding and coloration. It's a duplicate right down to the signage. It has working lights. It has windows you can look through to see the detailed interior that (thanks to creative use of mirrors and optical illusions) appears larger than its exterior. And it's entirely edible (except for the wiring and mirrors, of course).
