Eh...
That's a pretty misleading story, they're using lenses to focus the light to a point as it shoots to the next lens. It's not cloaking what's behind it, just focusing on a point. The two pictures are both missing obstruction of the center of the lens path, as it would then show a blowup of his skin. It's also directional, only works when you're lined up with the structured path.
The practical applications of prisms and lenses are numerous, but cloaking isn't one of them. Stopping light on the other hand is quite impressive.
Yeah, I said stopped. She's done quite a bit more than the blurb up top.
