Abstract
Self-similarity that a part of shape and the whole are similar exists frequently in nature and have characteristics which are not affected by the quantitative size while mixed with the element of surprise. Fractal is used to analyze such natural phenomenon. So I assumed if we incorporate the system of shapes which can be seen in nature into space design, we can create sculptures that include nature’s rhythm and bring pleasant harmony to natural landscapes. Given fractal which doesn't have its size a measurement, we did space construction by reproducing self-similarity program in CAD. Here, we not only introduce the attempts but will think about possibilities of its applications.
