The technology works by a video camera recording the scene behind you, and projecting that image on to your front, and vice versa.
This one has captured my imagination now for a while. There is a group at MIT working on this, someone was telling me they were working on this research a year ago. I wonder what commercial spinoffs this technology would have. I wonder what kind of policy issues this would result in?
We have No Cell phone zones now, no cloak zones? In our "age of terrorism" do we really want invisible cloaks? Seems like this would make assassinations and terrorist activities way easier. Although this stuff will be controlled by the government for a long time I assume.
