Rendition Cloth

From a dream I just had:

• Take the square LED clockface from a women's Apple watch.  Put four of them in a square.  
  
  
• Add a digital camera lens in the center where the four meet.
  
  
• Repeat this pattern over and over until you have a sheet of LED screens and cameras, a few millimeters thick but flexible.
  
  
• Make a raincoat out of this material.
  
  
• Display what the camera sees on the four adjacent screens.  
  
  
• Voila, invisibility cloak.
  
  
• Or, wrap a car in this cloak. You have the ability, via controls, to make your car blend into the surroundings.
  
  
• Or appear any color instantaneously.
  
  
• Stripes, polka dots, moving waves.  Make your car appear to be moving when its standing still.
  
  
• Make it appear to be a different car.
  

Not an invisibility cloak. For that you need to have the screens showing the picture of what's the other side of you, to create the illusion that the observer is looking through you. Your suggestion would turn the cloak into a mirror.
