Comic Book Technology
In the Marvel Comics future storyline, "Punisher 2099", one of the features of the Punisher's suit is "face-scramble" technology.
In this future world, security cameras are everywhere. Always watching. So to hide his identity, the Punisher's "face-scramble" technology digitally adds a skull image to cover his face on the recording.
When I first saw it, I thought that would be great with the concerns of "Big Brother" and the decreases in an individual's right to privacy. And it's only gotten worse since then.
Well, today German inventors have developed a similar technology using IR transmitters, which "blind" the camera.
Cool, very cool.
