Invisibility Cloak

I’ve heard the Canadians are working on an invisibility cloak. I can only imagine how such a cloak might work...The fabric is made up of tiny micro-hemispheres that act as both cameras and screens, each capturing and projecting light in all directions, and each in communication with all other micro-hemispheres. Using radio signals and computer software, each angle of light from each micro-hemisphere is routed to the appropriate micro-hemisphere angle on the other side of the cloak, which is always changing because the cloak is moving. A cheaper solution might be to use micro-mirrors, but then there’s the problem of how to tell the light to start and stop.
