The Vibe is played ambiently via unsolicited users by mining the entire Twitter network using the Streaming API, for tweets based on users emotional expressions ie "I'm happy that....".."Surprised that..." etc.
When a user tweets the Vibe directly, they take over the instrument and their tweet/ musical composition is played on the Vibe.
A user can tweet using their Twitter account or via Twitcam, where the Vibe streams live video / audio online of the instrument being played. Once a user tweets the Vibe directly their tweet is displayed on the Vibe's LCD display.
