This is a system made of springs moving under unary forces (gravity). The lines which are used as springs are converted to beams and are analysed structurally to inform the opening of the holes (smaller holes where more force is applied). This model was developed for the Simply Rhino Grasshopper Level 2 Class. It used Rhinoceros3D, Grasshopper, Karamba, Kangaroo and Weaverbird. It is based on experiments by Frei Otto, Gaudi and Jack Munro.
