Twitter-based Mood Light Using Arduino

Twitter seems to be invading all sorts of things nowadays, from the humble dress to satellites in space. Next up we’ve got a mood light that changes color based on a stream of tweets coming in via Twitter. The color is based upon the frequency of words such as “angry”, “happy”, or “sad”. The system uses an Arduino that collects data from Twitter using a WiFly module. The lights in this mood light come from RGB LEDs. What do you think will be connected to Twitter next?
