Isn't it scary to think all the ways "BIG BROTHER" is isolating and following us these days.
Faces can be picked out almost two blocks away in this one picture!!
This picture was taken with a 70,000 x 30,000 pixel camera (2100 Mega Pixels.) These cameras are not sold to the public and are being installed in strategic locations. The camera can identify a face among a multitude of people. Place your computer’s cursor in the mass of people and double-click a couple times (or 'finger-spread' on a device.) Scary sharp!! George Orwell must be smiling somewhere out there.
