Harry Potter cloak one step closer to reality

I know that we all here at Praise Science look up to Harry Potter as both a hero of science and of 'cool', now we're one step closer to seeing his magic invisibility cloak a matter of science-fact. Researchers at some smart school in California have developed a material using nano particles one billionth of a meter wide that bends light around an object, so that only the light from behind the object is seen. Not quite invisibility, but it would be basically the same thing to our eyes (even the great HP's cloak shows little ripples when he walks). Previous work in this area has been accomplished bending light at the microwave wavelength, but this new work bends light at the frequencies used by telecommunications companies, which are substantially closer to the visible spectrum, which makes this new breakthrough so exciting. It's just a matter of time, HP we're coming for you.
