The New York trends and innovation company PSFK publishes daily news on their website, which has 400 000 monthly readers. Last week Simon Mainwaring wrote the article “‘Powers of ten’ for the Twitterverse” about the impact of social media in the future. One of Mainwarings examples - together with Twitter, Facebook and Google Wave - is Emotional Cities, which he describes as follows:
‘Emotional Cities’ is the work of Swedish artist, Erik Krikortz that creates multi-layer, visual reflections of the world’s emotional pulse. You simply pick your current emotional state on a seven-level scale, allowing Erik to calculate and plot the average values for different cities, countries and the world in real time. In some cities, their emotional state is even projected on to a light installation, so you can know the emotional temperature of a city as you fly in on a plane. The social potential for this is staggering as it allows individuals, networked groups, entire cities and even countries to track their emotional states and virally affect others.
