“Twitter fountain displays thought bubbles of real thoughts floating up and away from the fountain in a cutting edge and original visualization within Second Life. The messages are answers to the question ‘What are you doing right now?’. The answers are then fed into the fountain creating an image of the ephemeral thoughts of people from around the world.”
This is a lovely example of how you can use virtual worlds as places to experiment with different forms of media representation. A fountain of Twitters isn’t at all efficient – but efficiency isn’t always the best way to get things done in a human way (DOS is efficient: a GUI isn’t).
