Twitter Emotion Graphs shows you the emotional state of Twitter in real-time.
From top to bottom the graphs represent: Happiness (Yellow), Sadness (Blue), Anger (Orange), Fear (Grey), Disgust (Brown), Surprise (Purple), Valence (Green/Red)
In the terminal you can see the full text of the tweets and the corresponding emotion values.
TEGs uses the Twitter Streaming API, Synesketch's EmpathyScope, and Ruby-Processing to get tweets streaming in real-time, compute emotion values, and display them in a visually dynamic fashion.
