DensityDesign Course 2013 / Tell a story about Milano

Our course at Politecnico di Milano started last Monday, and students are already working hard.
As first exercise, they were asked to visualize a story about Milano, using the new Open Data website www.dati.comune.milano.it
It has been a flash 48-hours exercise, have a look to results here!
Comments and critics are, as always, welcome.
