Can I become invisible? Someone probably thought of this already, but anyway... I'm wearing a full body suit. Small cameras on my back detect the wavelengths of light hitting me from behind. Many light projectors on my front emit light of the same wavelengths at the same trajectory as the incident light hitting my back. So anyone in front of me will see whatever is behind me replicated with new light. Of course, more little cameras on my front tell light projectors on my back to emit wavelengths matching those hitting my front. The light would have to be emitted slightly conically so the cameras in the suit get masked by the steady stream of light. This would probably warp the replicated images a bit, but maybe one way mirrors could be used somehow? The computers and power source are in a backpack inside the suit, and I must hold still to remain invisible. For now, let's say the suit is made entirely from cylindrical shapes, so no motors are needed to correct the light trajectories. When light hits any point on a cylinder surface, a reproduced light gets emitted from the point on the surface directly opposite. -Is this possible? -and how much would it cost?
