A new material that could be used to create a real-life Harry Potter-style "invisibility cloak" has been designed by British scientists.
The material, called "Metaflex", may in future provide a way of manufacturing fabrics that manipulate light.
Metamaterials have already been developed that bend and channel light to render objects invisible at longer wavelengths.
Visible light poses a greater challenge because its short wavelength means the metamaterial atoms have to be very small.
So far such small light-bending atoms have only been produced on flat, hard surfaces unsuitable for use in clothing.

My pet chameleon already has one.
......the ultimate hunting coat!
Now now.... I'll let you have a turn too.
My wife won’t let me. She is armed and dangerous.
They had materials that had a negative index of refraction for microwaves. Pretty neat if they got it for visible light now. I suspect it will only work near certain colors though. The construction is very wavelength dependent, like a radio dial.
Voldemort is not pleased.
This thread is worthless without pictures.
I always wanted to write that.
No pictures because... um... the cloak is uh... invisible.
