The world's first online Creative Think-In!

David writes puzzles for the Metro newspaper in London which we feature online in our puzzles section, and was also the clear winner of the Creative Thinking World Championship at MSO III. The first half-hour of the session will be set aside for your questions, be they about games, puzzles, creative thinking, television, radio, books or anything else; after that, David will lead some online Creative Thinking exercises. He'll have some challenges for you and will be willing to take challenges from all-comers. We'll explain more about this at the session itself, but it promises to be great fun. You won't need to bring any special equipment except an imaginitive brain!
