A famous architecture named Kiefer Technic Showroom Bad designed by Gleichenberg Austria.1 It is renowned of its unique design in adjusting the light or temperature in a room through control of any or all of the 112 metal tiles that grace the exterior making use of the movable metal tiles on its external wall. In comparison with the building, human’s biological process, eye blinking serve a similar purpose and function. Eye blinking is an action of opening and closing of eyelids by human rapidly in order to spread tears and respond to external stimulus that attack our eyes.
The opening up and closing movement of metal tiles of the showroom and human’s eyes are aim in adjusting in response to incoming stimulus, the light. Similarly, both the design of the building and the movement of our eyes made use of repetitive movement in adjusting the amount of incoming sunlight. When there is excessive light, the metal tiles as well as our eyelids extend and serve as a blockage in blocking the sunlight. Both actions are composed and facilitated by the cooperation of small units. For the building, there are lots of metal tiles and each piece of metal tile cannot function on their own. They must “cooperate” with each other in order to serve for one purpose. For example, in daytime, the upper metal tile extends to block sunlight, at the same time, the metal tile beneath it has to close up or extend for a smaller angle so that it will not block the movement of the tile next to it. Similarly, blinking of eyes is composed by small units which are the muscle of eyelids. Muscles are worked in pairs. In order to perform the function, one piece of muscle has to relax while the others contract or vice versa. Taking blinking as an example, eyelid muscles, Levator Muscle, Orbicularis Oculi Muscle and Frontalis Muscle2 has to contract and relax alternatively to perform blinking. Another similarity is the direction of movement, both the metal tile and human eyelid move
