Invisibility cloak

As I’ve mentioned many times before, the not-so-distant future is going to be a pretty cool place. Professor John Pendry, from Imperial College London, says with funding an invisibility cloak could be available within five years (via digg). The cloak would be made with metamaterial from nanotechnology, so that it could change the direction of electromagnetic radiation - it would neither reflect light nor cast a shadow:

Light waves would flow around an object hidden inside the metamaterial cloak just as water flows virtually undisturbed around a smooth rock… Whatever direction it is viewed from, the light bending round the hidden object would make it appear to have vanished.

I can’t wait to get one.
