With the idea of GC parametric model, the variations depending on movement of paper model are analyzed. As the center square rotates 90 degrees, the arms around the square spread out. the total rotations is 90 degrees as well. The steps are divided into 6.
By pulling and pushing the unit model, the middle part of it rotates, and some variations of height and pattern on it are generated. As it's aggeregated with two different phases, the boundaries around modules change.
