Open-source architecture to house the world

Here is a very energetic talk (filmed in February 2006) by Cameron Sinclair hosted at TED talks. He is part of the Architecture for Humanity organization that promotes architectural and design solutions to global, social and humanitarian crises. A very inspiring example of how internet really makes the world small and how ideas like crowdsourcing and the open access to innovation can make a difference. The first time I heard about a creative commons house design.

They have started a project called Open Architecture Network to serve as hub for collaborative efforts.
