GEAS - Global Extinction Awareness System. This is a very interesting project where people gather/ join and try to solve problems of the world and making up different scenarios of what might happen to the world in 2019.
This program started on 6 of October 2008 and will last 6 weeks. People can join in and play the game, however the archive will last for a long time and will be researched on if the scenario could prevent things and also help the survive rate of the humans.
So if you are a theorist, futurist or just someone with a big fantasy join in and you might save the world. Join in at superstructgame.org.
