How Derren Brown Predicted The National Lottery Numbers

Derren Brown a few months ago supposedly predicted the National Lottery numbers. This was a great event and there has been much speculation as to how he did it, but now an explanation has emerged that I think is rather convincing. I don't feel cheated knowing what the fake is, I actually find this side of magic fascinating.

A good explanation of how. Do you feel cheated? I didn't.
