From Metagovernment - Government of, by, and for all the people
MetaPlan uses a set of cards in different shapes and colors. The discussion leader explains the goal of the discussion. Each discussion participant gets a handful of cards. Maybe yellow cards are used to define categories, and red cards for the ideas. Everyone is obliged to write down one or more of his/her ideas about the discussion subject on the red cards. A large pinboard is used to pin up all the ideas. More and more yellow cards are added as headers for categories. At the end there's a structured view of everyone's ideas. The result will be photographed as graphical journal. The method guarantees the esteem for all ideas. Thus it's a good method for getting into discussion of complex topics in a manner of direct democracy.
