Lately, it seems like you can’t click on a handful of links on the internet without running into some kind of prototype invisibility cloak. Though this device can now be added to that list, it’s more like a cube than a cloak, and something out of the ordinary — even for a notion that is as abnormal as becoming invisibile.
Invisibility cloaks seem to run rampant nowadays, but even though they’re “common,” none of them are like what you see in the movies. There isn’t a thin sheet of fabric that you can toss over your head and then completely disappear, with your arm becoming visible when you reach out from under the cloak to grab something. Recently, at TED2013 in Long Beach, California, assistant professor of physics at Singapore’s Nanyang Technological University, Baile Zhang, showed off a little device that has the same outcome of an invisibility cloak, but isn’t a cloak in the least. The device is a little cube, only a few inches in height, but ably performs its function. Zhang seems to be using the term “cloak” not to refer to the garb, but the action. This is fine by us, because look at it go:
