altho i'm a grammar nazi, i'm totally with you on this; it seems pretty fragile for many, many use-cases, as well as probably easily technically circumventable.
consider even the darkened movie-theater case: there's going to be a lot of legitimate CCDs facing the screen - people checking their politely silenced cell-phones.
if you've ever directed an LED laser-pointer towards your own face in the dark, you'll know that the beam is highly visible and pretty disturbing! i don't think that'll sit well with movie patrons.
w/r/t daylight applications such as blacking out protests, altho it may be theoretically possible, i highly doubt this technology will perform well. also don't forget that in such scenarios it can be easily overcome with a $7 disposable camera.
Well, no kidding, but the article didn't say "absorbs all the light",
it went out of its way to use the obviously ambiguous term "essentially erased".
This is a clue that there's more to be understood here than they're willing to put into a short and lay-person article.
IIRC about two years ago negative indices of refraction had only been achieved in the infra-red spectrum, but that may have changed by now.
yes, you'd think they'd need a plural lens!
mod this up !
.. you know where. but, uh, boy, about those puns !

ditto.
that's the better way to do it, allright.
