Create a Facebook app that:
Shows a realtime Economic Graph just like Moniac Computer at the LSE
Shows a realtime Quality of Life graph. (for you the user)
When there is a problem with the economy or a problem with your quality of life – the app allows you to data mine and follow the path back to the potential causes of the problems.
Maybe allow the user to modify the balance of a simulated version to test the impact of any potential polices.
