1) The Chair provide a model of a chair - then anything goes. Create a scene that tells a story but it must some how involve the chair (or a different object). Got the idea from a uni project we had which was based on a desk. This would leave room for people to make the idea there own. 2) Caricature I think a caricature challenge would bring some really funny entries. - could be off ourselves or famous peeps. Well as long as it not Chef Gordon Ramsay I`ll think of some others aswell ...
