Metamaterials, AI, and the Road to Invisibility Cloaks

You don't need metamaterials. There are various patents on "invisibility cloak" systems, and most of them use screens and cameras to project what's behind the wearer onto the front-facing screen, e.g.: https://patents.google.com/patent/WO2016160588A1

Some others, mostly intended for military vehicles, aim to match surface IR emissions to the background.

Using metamaterials -- which need to be printed or, even worse, made with lithography techniques -- adds unnecessary cost and vastly increases complexity.

Minor thing but how cool to use this on pillars of cars and have total visibility ?

More than an invisibility cloak, I'd like to be able to "paint" my house with a programmable material that could change color/pattern.

So confused when I read invincibility cloak.
