The "Sentiment Analysis" is displayed on 41 LED bars in the Media Garden via 125,952 lights, total. It's fed by 2.75 km (2 miles) of fiber-optic cable, and represents total Twitter activity with fountain-like patterns of lights, including bright bursts during busy periods. Every 10 minutes, that data is sent to a dozen video walls inside, where the six emotions are displayed as specific color patterns. The idea is to show "the evolution of the global emotional state ... which will go on to form the emotional memory of the three months in which Amygdala will be deployed," according to Fuse.
The display is accompanies by sound textures representing the six emotions that start out distorted during the Sentiment Analysis. They gradually progress to clear tones corresponding to the strongest feelings and form a Twitterverse melody of sorts. It's designed to let you experience the world freaking out in a surprisingly zen way, as you can see in the video below
