Twitter Mood Light - the World's Mood in a Box

In this DIY activity the Arduino connects directly to any wireless network via the WiFly module, continually searches Twitter for tweets with emotional content, collates the tweets for each emotion, does some math, and then fades the color of the LED to reflect the current World Mood; Red for Anger, Yellow for Happy, Pink for Love, White for Fear, Green for Envy, Orange for Surprise, and Blue for Sadness.

If an unexpectedly high number of tweets of a particular emotion are found, then the LED will flash to alert us to the possibility of a world event that has caused this unusually strong emotional reaction.
