Etsy seller LIMOchi makes these killer "poly leather" TARDIS purses to order for all your time-travelling bits and bobs. The seller claims that they are, indeed, bigger on the inside than they are on the outside.

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
