That is cool. Though they're talking about cloaking microwaves.

I'm trying to visualize what a cloaked object such as the ring in the article looks like to the naked eye.

Well, they do have a photo of the ring in visible light right there in the article.  |

Actually, a visible light spectrum version has been developed and proven. A photo of the prototype in operation is below:

So that's how Harry Potter's cloak works! Who'da thunk it?
Very interesting article.
