The AP reports that GCHQ -- the British cryptologic agency -- has posted a puzzle on its Web site. If you can solve the puzzle (it's at http://www.gchq.gov.uk/challenge.html), they want to talk to you... Of course, the AP quoted a former MI5 agent as saying "The kind of people with lively minds this appeals to will soon discover that this kind of thing is all done by computer anyway."
