There’s a fun hidden treat for Doctor Who fans on Google Maps.
Track down the ‘Police Telephone Box’ outside Earls Court Station (OK, it’s here) and all may seem normal. However, drag your Street View guy directly on top of it (or, in some browsers only, click the double white arrows outside) and you’ll be taken inside the TARDIS, which is, indeed, bigger on the inside than it looks on the outside. Fun!
