For a few years at least there have been some types of cloaking devices out which the DOD has used in some situations. One of the types I am aware of is a cloak which has tiny sensors which display what they see on the other side of the object. So, if you were next to a grove of trees, the device would display the trees on the proper side. They say it looks kind of like a heat wave if you see it in broad day light. I know it was used to hide an APC in one case during broad daylight. Interesting find though.

Old news, in fact there's a cloaking device for sale in Ebay right now.

Here:

Hahahaha

Link?

Interesting topic though, the technique relies on nano-patterning materials, the patterns create highly defined surfce plasmons (electron density waves) that interact with light of very specific wavelengths - it's tricky to see how a material such as this could be 'tuned' to cover enough of the visible spectrum to make stuff invisible, or even enough of the radio spectrum to make a plane/tank radar invisible.

How well does it work when the object is moving? Or does that have no hindrance on the effect at all? I mean, you put this on a F-18 going Mach 2, would the sensors be able to keep up? shrug...

Either way, we all know none of us are getting this, so stop drooling.

It has existed for a year er so, in a somewhat more simple yet similar fashion
http://science.howstuffworks.com/invisibility-cloak2.htm

It's actually real, the cloaks are made of thousands of reflecting spheres that reflect all the light around them.

Here are some videos of it in action

hmmh...

According to the laws of physics as presently understood, an invisible person would necessarily be blind, no matter how their invisibility were achieved. In order to see light, it must be absorbed by the retina, but in order for a person to be invisible, the body must not absorb any light. In fact, according to the no cloning theorem of quantum mechanics, they could not even make a copy of the photons so they could see one copy and allow the other copy to pass through or around them.

what good would it do to be blind? kinda takes ALL the fun out of it. but, that statement is based on cloaking where light is not absorbed at all... would that be the case with the whole "project what is behind you" deal? i don't think so.

... but those videos, especially with the skeleton and all... looked kinda hokey
 
There is more to life than just sight. If you have the tech to go invisible then you have the tech to turn sound waves into SONAR like images capable of being processed by our minds. (Shadow world anyone?)
