this assignment is about creating a machine reacting to external data of environmental forces; we decided to design an abstract rounded facade with a vertical perforated louver system for shading in hours with increased radiation from sun. Depending on the position of the sun and the resulting angle between the normal vector of each single louver and the sun vector the louvers adjust their position as soon as a certain threshold angle is or under- or overrun; the final turning angle is then extracted by a listitem and transfered to fire fly which allows the data based control of three servos in a louver mockup.
