Arborism from Japanese Nosigner is a table and chair which has legs formed as tree branches. The design of the legs has been configured by the fractal algorithm called "Tree Curve". Therefore, the design is an exact reproduction of the branch structure of real trees. The interesting factor of the design process is that it was completed not by the arbitrary work of the designer but by the natural logic of the nature itself.
There is a leaf pattern on the top of Arborism. Their positions are defined by a few rules. The rules are that they should not overlap each other and that there should be a maximum density, to remind of the real tree’s leaf. Following these rules, suitable geometric patterns arise. From this point of view, the top pattern of the Arborism is considered to be close to the rules of nature.
