it's interesting how a complex process is performed without a hitch using very simple means. we're talking about a three dimensional deformation. if you asked an engineer to do it he would install twenty joints. here you just depress to spines and the wings open up that's a clever design work three thousand times it might look flimsy but it doesn't break it's astounding we knew we just had to do something with it. this model made of a wooden stick and a sheet of paper can be used to demonstrate the mechanism. you bend the spine and that makes the wing move sideways so that's the idea behind a new architectural shading system which i don't need to include. the secret skills of the brilliant plans can be massively upscaled. that innovative shading system was incorporated into the kinematic facade i suppose million built for expo two thousand and twelve and you also south korea.
