My gall bladder has got the better of me, so I've retired to bed with a good book: "The Art of the Infinite" by Robert and Ellen Kaplan.
The Kaplan's have put a lot of effort in to making math popular - there's a short BBC profile of the couple here. Notice the BBC reporter sent to interview them makes a point of mentioning how bad he is at mathematics - as this BBC report makes clear, a lot of people in Britain are strangely proud of the fact they can't add up.
Go figure.
