As you all know by know I'm fascinated by innovations in camouflage, spinning fans and blinking lights. Here is another camouflage experiment by the Australian Ministry of Defense that is about developing a skin that allows the user to manipulate the color and pattern by applying voltage across the film see http://www.zdnet.com/au/defence-begins-research-on-adaptive-camouflage-7000002255/
The target user for the project is a vehicle or ship but would it not be able to apply similar technology to clothing or other objects.
The difficult part according to the article is getting the sensor programmed so that you have a feedback loop on what the environment is like.
Has any one heard of anything else out there of interest in this area?
