@Ragman,
Actually Ragman it is based on the idea of a Turing machine,basically the idea is that you ask questions from a hidden box, if you can't tell if the answers are from a machine or from a human then you have created artificial intelligence. I find some reactions quite strange: there is a lot of hostility. i am carrying out and experiment not an excercise in self promotion. Your I don't care was a beautiful statement of "it's what inside that counts". Some of the more recent ones seem petulant and churlish.
