New 'invisibility cloak' is remarkably effective

A Canadian company has come up with a new material that can render large objects almost totally invisible.
Known as Quantum Stealth, the new invisibility cloak takes the form of a thin, inexpensive material that makes objects vanish from sight even though the background is still visible.

Requiring no power source, it works by bending the light in a very specific way.

The brainchild of Canadian camouflage design company Hyperstealth Biotechnology, the new material can conceal the presence of entire vehicles and could prove invaluable on the battlefield.

It even works for non-visible wavelengths from mid- and near-ultraviolet to the infrared.

While it's not quite Harry Potter, the technology in nonetheless very impressive.

A video demonstrating the material in action can be viewed below.

Very cool. I fiddle around with optical illusions (and mirrors) for example u can take something like large vanity mirror, put in middle of forest, almost easily create illusion of invisibility. I'm curious if there's another cloak on opposite side of wall. Illusions can be wickedly deceptive yet simple.

I want some! Hopefully a few talented visual artists will get to play with it in the near future. I'd love to see this stuff in museums much more than as a tool of warfare...

I need the exact opposite - a screen that makes it look like I'm actually at work!  Something life-size, made out of lightweight material like a large board of... card?  And then cut to shape.  Wow! I'm gonna patent this technology as soon as I perfect it.  Now, if only I had a catchy name for this?   wrt the material - it certainly is clever: the screen is collecting light from the edges at the back of the curve and carrying it to the front.  This is very much the way fibre-optic bundles have been used in endoscopes for decades, but I suspect these screens use thin sheets.  Note how i...

Wow. I wonder if one can buy a small paper-sized sheet of it to play around with, or, maybe it's restricted or too expensive.

honestly big deal. see how the "cloak" has to be curved? well there is a focal point of that curve and its about 20 inches behind it. when objects are close to it it doesnt work. its probably that plastic that has those groves in it that they use for those 3D shifting illusions on kids toys...the ones that you look at one way and then as you move your head side to side the image shifts and looks 3D. cool, but definitely not high tech.
