As if gold prices weren't heading up already

A Russian scientists claims to have invented a "cloak of invisibility" as a by-product of nanoparticle research.

The so-called invisibility cloak, created by Oleg Gadomsky, is called “The method of conversion of optical radiation” in the patent.

Gadomsky had been long experimenting on nanoparticles of gold. Thus, he invented a sub-micron stratum of microscopical colloid golden particles that makes an object placed behind it invisible for an observer.

He admits he hasn't got all the bugs worked out, but he's working on it. Wonder what one of those cloaks will cost when all is said and done?
