The one I chose resembled the picture here called 'The Exquisite Corpse' - a collaborative surrealist technique, rather like the game of consequences I used to play as a child. Reading about it I realise I also used to use it to generate ideas when I taught creative writing. Each participant would invent a characteristic for a character - and this character, generated randomly, could be used in a piece of writing.
Tim Jones of Imperial College, London*, has used the technique to generate pictures of what science means to various individuals and has made a film of the result. Now he wants to expand the project to include other people. The instructions on how to get involved in what could be the biggest Sci-Art Project in History are here - and I definitely intend to have a go as soon as I get the chance...
It is open to anyone. All you have to do is draw what science means to you and send it in.
