I would also add that the 1956 Godzilla was better than the new Godzilla, although I still have trouble with the original in one aspect. How did that scientist think that showing a girl how he could kill tropical fish and turn them into skeletons would impress her?
Back to topic. I read an article in the Austin-American Statesman about 10 years ago about a high school student in Round Rock who had the idea of making cars invisible by using a series of cameras on one side with mirrors and a projection screen on the other. Also, George Lucas used a takeoff on this in the original Star Wars, by putting mirrors on the bottom of Luke Skywalkers car so it would reflect the surrounding ground and hide the tires. So, you're right, this is way old from a conceptual perspective.
