The online game Lemonopoly was launched in the San Fransisco bay area, a region traditionally rich in citrus fruit. Unfortunately, lots of fruit goes to waste. The game challenges tree owners and residents to make better use of the fruit, sharing it and making things from lemons, limes and oranges, such as lemonade or marmalade. As such, scoring in the online game promotes a new social citrus culture in the real city. In July this year, the game will be fully functioning, providing a point system for sharing lemons, adding trees to the map and making things with citrus fruit.
