Researchers at UC Berkeley have successfully built a very, very, very small invisibility cloak. The experiment concealed an object that was about one-thousandth of an inch. It works by affecting how light would typically bounce off a three-dimensional object. Normally light becomes distorted when it does this, but the cloak reroutes the light to make it appear is if it is coming from a two-dimensional object, basically making a flat mirror appear. Even better, they said the cloak could be programmed to match the background behind the object. The cloak is made of an ultra-thin layer of gold blocks that make this magic possible. What's the point of draping yourself in a pimp gold cloak if no one can see it?
