There is an interesting article about face recognition cameras and software at TechRepublic that cites a few interesting projects and makes a good point about the advances of the technology.
I talked to a few people that know well the camera systems in London and I understand that they now can track anyone around the city automatically.

I read a wonderful book “Rule 34” by Charles Stross recently that I can wholeheartedly recommend. The book’s action is set into the future but that is the future that has all the technology of today, simply deployed overall. It is not such a far-fetched story any more than the article linked above.
The spread of surveillance calls to life such things like counter surveillance clothing fashion. I think when it is in the fashion, it is not new any longer, is it?
