This is cool coupled with disturbing. I don't like the idea that some unidentified government agency can monitor me picking my nose; isolating out of a group of a million people.
As I was not in Washington DC, but here watching on TV I guess I have nothing to worry about. However one does wonder if the government can zoom in on so many; if they can tap our phone lines and cell phones; are they above installing chips in our digital TV's to monitor our couch potato stances and conversations.
You can be sitting there in your rattiest nastiest pair of PJ's thinking you are in the privacy of your home and low and behold there is a group of people secretly mocking you on the other end of your television set; not a good thing to overly contemplate as it might make you go insane :)
You can scan and zoom to any section of the crowd. . . wait a few seconds. . . and the focus adjusts.
