CNN has come up with a really amazing data visualization for tweets being generated at the COP17 Conference on Global warming. The concept is really pretty simple, tweet and add the hash tag #COP17. Your tweet is added to the visualization engine and based on the number of re-tweets, comments, direct messages etc. you get to watch your ideas and thoughts grow. To tie this back into the conference itself, CNN is projecting the entire visualization as a hologram inside the conference itself. The embedded video below gives you a pretty solid idea of how this works, and to participate go here.
