MIT professor Joi Ito describes how he collaborated with strangers to build a radiation sensor network after the massive 9.0 earthquake in Japan in his TED talk. The project occur out of a need for the safety of the families of the people involve. He says that it would have been very difficult to plan and build such a network before hand as he did not know of the people that eventually contributed to the project. He advocates spontaneous project and become now-ists.
