Active and re-active camouflage is an interesting concept of course like many other concepts borrowed from nature. As predators and prey conceal themselves to prevent being detected or eaten. Those who are best able to camouflage themselves stand a better chance of fulfilling their lifes mission. In warfare it is the same scenario, as each side tries to hide and attack or ambush the opposing forces.

Active Camouflage is an interesting concept indeed and I completely enjoy the MIT work on that and the young Lady who has discovered lots of applications for such including going out on the town with such attire to set mood and mirror those around you. The James Bond movie I believe depicted this in a positive light with the cloaking of a car?

And of course we do not necessarily have to see something to know it is there, as we have many types of other sensors to make up for our lack of vision to see what is there or is not. A thought or series of them for you to contemplate and thoughts on this matter;

It makes sense to spend research and development monies on such things as re-active and active camouflage and to understand that things can be there that we simply cannot see? Consider all this in 2006.
