The peak oil crowd might want to check this out.

World Without Oil is a serious game for the public good. It enlists the 'collective imagination' of Internet users to help us confront a real-world issue: the risk our oil dependency poses to our quality of life. It's the first major "alternate reality game" to use immersive collaborative storytelling to build a vivid, realistic vision of a possible future.

Here's how to play:

(1) Imagine your life in this oil shock.
(2) Create something on the Web to express your reality: a blog post, an image, a video, an audio file.
(3) Tag it "worldwithoutoil" so others can find it.
(4) Tell us about your creation by emailing it to us. Be sure to include a link to your story!
