Cephalopods (e.g. squids, octopuses, cuttlefish) are able to actively adapt their appearance in terms of color, texture or transparency. The goal of this project is to mimic this ability with a simple and mechanical solution and apply this technology to a product or environment. This resulted in a pneumatic mechanism which folds open after actuation and thereby changes color. This mechanism was then applied to a wall panel which can be used to cover the inner or outer walls of buildings and thereby change the color of the facade or space.
