Excuse the mess, I wasn't expecting visitors, but this is my bedroom. Yes, I live in an oak-panelled library. Except it's not oak. It's not even wood. But no, it's not fibreglass or plastic. The material used is far, far cooler than that. The room was decorated in the thirties. So what is it? I'll tell you what it's made of next week, but let's have some guesses.

Out of shot is the huge, intricate ball-shaped wrought iron chandelier which dominates the room. But look closely and you'll see the bakelite servants' bell. [And, no, the walls are not made of bakelite.] Look even closer, of course, and you'll see a half-eaten sandwich, but please ignore that.
