I'm a big fan of Gary Larsons' Far Side. I'm devising a system to create Far Side style cartoons: there would be a sister planet of planet Earth that would be 'Far Side World' that exists in the spirit of Far Side cartoons. Sometimes funny and absurd things would happen and sometimes 'normal' things would happen. The creative/cartoonist would be able to 'pick off' the funny events and make Larson-style cartoons from them.
The project would be good for any creative brainstormer, as the absurdity and surrelism of events would allow them to be more comfortable with absurdity - such as the absurdity and deferral of judgement required when making a provocation advocated by de Bono's lateral thinking provocation method.
