It is wonderful to see that the world of biology continues to offer insights to engineers. We've long been familiar with the use of countershading and disruptive patterns to make objects less conspicuous, but this is certainly taking the lessons from nature to the next level!
This is interesting how technology can be used for military camouflage. Nature teaches us so many things that if rightly mixed with technology can be used to develop the same defensive techniques that animals use. It will interesting to know more on design concepts, not sure if they would share it.
