Presentation; social mood mapping

I thought I would post up this video because it's very interesting. Although probably not the future of search engines, it's a good example of internet based experimentation and the applications of these ideas can be found from arts to social mapping and opinion measurement.

The presentation of the information is great, and although it cannot really give a true picture of the worlds feelings as; bloggers, or even those who write 'I feel', are not really a strong representative selection, however lets not let that detract from some really interesting and hopefully positively progressive, ideas.
