Geek stuff, sci-fi... Since all you boys and girls watch Star Trek: "Physicists Nicolae Nicorovici from the University of Sydney, Australia, and Graeme Milton, from the University of Utah, have proposed that devices called superlenses could be used to create a type of cloaking device. Using a principle called 'anomalous localized resonance', superlenses placed very close to a small object could mask its reflected light waves by resonating at the same frequency, much like how noise-canceling headphones mask sound waves by creating a sound that is at the same frequency but inverted in phase."

Wouldn't that make the object look black?

For "cloaking" you'd need to cancel light reflected from the front while transmitting any light that lands on the other side of the object (for any angle it could be viewed at, without distortion and with a minimum delay between back reception and front transmition).

The easiest way to do this would be to bend the light waves around the object rather than masking any of light waves. For the simplest case (a fixed view angle), this can be done with 4 standard/boring mirrors.
