I don't remember reading about this before. "You might have seen a post from our friends at Soldiers Systems Daily back in December about a new concealment system developed by camo savant Guy Cramer that literally changes its color with the background of the wearer. SSD had few details at the time, basing their post on Cramer’s release on his Hyperstealth company web site. But Kit Up! got a chance to talk to the mad scientist himself at the ADS booth during SHOT Show." Read more: http://kitup.military.com/2011/01/chameleon-camo-is-here-maybe.html#ixzz1BuCEdCOd
This has been the modern holy grail for camo, be interesting to see if it truely works, but then if it truely works, could we even see it?
While this isn't exactly "on point", a few years ago I was reading a Popular Science which was predicting that in the "near future" the tech would exist for suits of camo to be a series of tiny video cameras on all sides of the units which would take pictures of what was on that side, and then project the image to the opposite side using small square LED flat panels. This way the image of what was behind you would be on your "front", the image from the front would be on the "back" and so on. They were speculating that this would most likely remind people of the "suit of the predator" in the movie of the same name. Of course cost and durability would be major concerns, but the concept was sound.
I'll see if I can find the article in the next few days. One of the things they were troubled with was "how to hide the weapons" using this system. I mean men would still be carrying rifles and stuff. You cannot have them just "floating" around or the effect is wasted. But still.....
