Drop what you're doing, friend. Cloaking devices are real now, meaning all we need are force fields and some spandex jumpsuits and we'll be bonafide dwellers of the future. The good news comes to us from physicists at the University of Maryland, lead by Igor Smolyaninov, who successfully cloaked a 10 micron gold ring by bending two dimensions of visible light. This follows up successful research last year that had worked out an invisibility cloak in the electromagnetic spectrum, but is still a far cry from a true 3D cloaking device, since such an object would have to bend light waves both magnetically and electronically simultaneously -- this 2D model is just pushing around "surface plasmons" created out of the light waves. While the tech probably won't make the jump to 3D cloaking, it might be used in computer chips or as a replacement for fiber optics some time down the road, which we suppose is alright.
