I thought this would be of general interest ... I haven't looked to see if for real or how viable, however a-priori I believe this technology is very possible.

University of Central Florida (UCF) scientists have created the first large-area metamaterial (cloaking material) for the visible-light spectral range. (http://www.kurzweilai.net/how-to-create-a-large-area-visible-light-invisibility-cloak)

5000 Lumen LED torch = $50

It's only a war crime if you're at war :D

Metamaterials are incredible. Not only can they do things like create cloaking in different parts of the EM spectrum, they can create sub-wavelength superlenses and something called phased-array optics. Apparently that will enable them to create holographic surfaces so realistic you could look at it from 6 inches away with binoculars and not be able to tell it apart from a real scene.

Not impressive enough? Ok. Well, scientists have already used metamaterials to create ARTIFICIAL BLACK HOLES (http://www.technologyreview.com/view/415718/artificial-black-hole-created-in-chinese-lab/).

They could also be used to simulate the Big Bang.

Shit's about to get crazy like people don't even realize.
