An app that recalculates land prices in Ginza through a participatory mechanism. Users of the app contribute by specifying points that they deem as lying on the "outer edge" of Ginza. Using that information, the app computes the geometric center of Ginza, and adjusts land prices within the district based on each point's distance from the center.
