Econundrum is a shared physical system, designed to visualize the carbon emissions as a result of dietary choices. People of a community can indicate on their phone what food types they ate that day, which will be visualized on the physical installation. Every disk represents the impact of one person, and its elevation indicates the level of impact: higher is fewer carbon emissions, lower is more carbon emissions. The highlighted food types visualize how the 'foodprint' of each person is composed. The different sized circles within the disks show the impact ratio of the different food types, which could be used for choosing alternatives to decrease carbon emissions.
