Chromatophores just make things cooler

Evolution has been very kind to cephalopods and chameleons. For years scientist thought the primary purposes of camouflage via chromatophores was to evade predation and/or aid in hunting. Turns out, especially among cephalopods, the color and texture change allows the creatures communicate with one another while keeping their anonymity and exposing themselves to predators as well as present themselves "more attractive" to possible mates. Using chromatophore technology, albeit somewhat far-fetched, seems really useful for the military and soldier's safety, or me sneaking into Heidi Klum's bathroom while she showers.
