Urban Heartbeat of European Cities – Urban Mobs
During major events, people use their mobile phones to share their emotions: the euphoria of a football match in Spain or Romania, World Music Day in France, or Saint John's night in Poland. We want to share our excitement, so we call up our close friends and family. Urban Mobs allows us to see this activity in four major European cities - this "urban heartbeat" so to speak.
So when is someone going to do something for the United States?
