Cherrie, the link above didnt work for you cause in its URL you have also the ' "] ' included. Copy just the link and paste in in your brwoser and it will work!
I though I would add to Anu's theoretical article a real image of invisibility cloak which was introduced 2 years ago in 2004:

In the above link you can see the photo of it 
Cheers,
H.

hey Cherrie !
sorry i tried to put the link correctly but i dont know why it is still not working 
anyway you can copy and paste it in google and view it.
Thanks Hayk for the visual treat of the Invisible cloak
this can be really explosive for Spying. I hope it is not put to bad use. but technology has its own side effects.
Now i think i shouldnt have watched that creepy movie called Hollow man!
and if you are watching a creepy movie you should sit through it and see the good end . But unfortunately i never saw beyond the first half...so i still dont know whether everything ended on a positive note or not ?
cheers
Anu

updates on invisibility cloak...
[link="http://news.bbc.co.uk/2/hi/science/nature/6064620.stm"]
A US-British team of scientists has successfully tested a cloak of invisibility in the laboratory.
The device mostly hid a small metal cylinder from microwaves in tests at Duke University, North Carolina.
It works by deflecting the microwaves around the object and restoring them on the other side, as if they had passed through empty space.
But making an object vanish before a person's eyes is still the stuff of science fiction - for now.
The cloak consists of 10 fibreglass rings covered with copper elements. This is classed as a "metamaterial" - an artificial composite that can be engineered to produce a desired change in the direction of electromagnetic waves.
The precise variations in the shape of copper elements patterned on to the ring surfaces determines their properties.
In the experiment, the team used microwaves to try to detect the metal cylinder within the cloak.
scary????

Not really scary, not yet. Negative refractive index-based "cloaks" have to look more like invisibility sheds than cloaks due to the physics of how it works (the invisibility shell has to be thicker than the thing it is supposed to hide for reasons that are WAY to involved to post). Now the active camouflage suit that mnopq linked to, (how it works can be found at [link="http://science.howstuffworks.com/invisibility-cloak6.htm"],
that looks scary but actually requires a very elaborate setup involving a video camera and a projector that uses the subject like a movie screen in a theatre.
In short, it will probably be at least another decade before its time to worry about invisible spies. Still, law enforcement and military operations will have to change enormously when it is perfected, and there is so much money going into this that it is only a matter of time before they make something useful. I am not looking forward to the prospect of invisible bank robbers and muggers, and I think that invisible secret police spying on people would be even worse!

Hi
This is a kool stuff...it is part of what I call deep thinking...not settling for the existing....innovations!
Above all, I see a very deep use of the laws of light from the elemetary physics viz refraction & reflection. Therefore, we can deduce clearly that from any of the existing elementary physics theories, we can make numerous wonders.
Friends, I think there is more to invent in this our dear world.
Can you think of the day our cars will be powered by Water (H2O), or common atmospheric oxygen.
I believe people are already working on all these now.
Friend, we can also contribute to these wonders...

Yes , I dont see much use of the Invisibilty cloak for common good !
There are better things waiting out there for attention and money ! like the things mentioned above ...a vehicle that runs on water or an invention that converts ocean wave energy into megawatts of electrical power etc ...

Complicated and highly technical.
I will just use Harry Potter's invisibility cloak on innocent people in war torn countries (so they can move from a safer place), battered women and children (so they can always hide from their offenders), and biological weapons and other destructive tools (so that they will not be used in anyway).

Remember only twenty years ago the best computers took up a ballroom and had less than a hundredth of your PC's processing power.
I would probably do a bit of espionage with an Invisibility Cloak.

It could have many good uses for reducing 'visual pollution' . Many people are against wind turbines because they disrupt the scenery. But invisible wind turbines.... Dangerous for planes but not ugly on the landscape.
Could be used for many bad/evil purposes also, but its still a while away yet until you can walk down the street in your invisible cloak.
