How to Make an Object Invisible

According to this article in Technology Review, we're one step closer to having invisible objects. The object in question is covered in nano-scale wires that have a negative refractive index. This can make light wrap right around the object and continue on as if the light wasn't even there.

This isn't exactly Harry Potter invisibility cloak stuff (this test only works for one frequency of visible light and you can still kind of see the object, but it's definitely a breakthrough.

I'm no Luddite. Industrial progress pollutes you and me w/toxins. Federal regulations do next to nothing to protect us from this. We don't need anti-fog glass any more than we need electric can openers. Carry a cloth in your car to wipe down your windshield. Call me old ashioned. There's a big difference between auto safety and gratuitous "convenience".
