"Flexible scalable displays change color, convey information, send messages IR radiation... inspired by morphing chameleons and octopus skins... capillary-controlled robotic flapping fins... 1,000X more energy efficient... controlling volume and temperature fluid-filled pixels. Varying fluid volume within pixels changes flap flip directions... varying temperature allows pixels communicate via IR... send two simultaneous signals—one seen with human eye and another seen with infrared camera"
