<!--StartFragment -->It may not have the futuristic looks of Enterprise, or the apocalyptic weapons of a Death Star, but Doctor Who fans will know well that looks can be deceiving.

For, step over the threshold of this police box and you?ll find yourself in a Type Forty time capsule, stolen from the Timelords by their renegade prodigal son, the Doctor. Dimensionally transcendental, this Time And Relative Dimension(s) In Space piece of kit is bigger on the inside and was stuck in the shape of a Police Box when the Doctor visited London in the early sixties (it should disguise itself to match its surroundings).

So attached is this piece of street furniture from another era to the show, and so long have the copper?s lock-ups and phone points been absent from UK streets, to many children the Metropolitan Police Box is the TARDIS, pure and simple.

Evocative in its incongruous appearance amongst various alien landscapes, the TARDIS signals the start of a new adventure in the longest running science fiction series in the world ? and like many of the show?s groundbreaking devices and images, has become so commonplace in our culture that we almost forget the magical imagination behind its creation.

With a wheezing and groaning sound, the TARDIS has landed for a strictly limited time as a desktop cut out.
