O3 Moods is a Node.js Express web application that uses the IBM Watson Personality Insights API to analyze tweets in order to gain personality insights that are used to determine a user's mood and return a color representing that mood. If the Phillips Hue Bridge is set up with the Meet Hue Developer API, the bulbs will then dim to the color representing the mood.
