Once again it has come to this time of month. In twelve hours' time, you can see the cipher here: http://cp4space.wordpress.com/2012/10/23/cipher-3-chess-cipher/ Of course, if you're slightly less patient, you can follow this direct link to download the image now: http://cp4space.files.wordpress.com/2012/10/chesscipher.png There's a MathsJam at 19:00 BST on Tuesday, which takes place internationally (mostly in Britain, but also in the USA, India and a few other countries). I might be able to attend the Cambridge one for a maximum of 20 minutes or so, since I have another agenda at 19:30. Sincerely, Adam P. Goucher http://cp4space.wordpress.com
