Knot Knot is a lighting collection based on multiple traditional Chinese knotting techniques. Various Chinese "Jie" (knot) types have been studied and applied to both functional and aesthetic aspects. The inner layer, structured with the Chinese JinGang Knot, serves a functional purpose by diffusing LED strips, while the outer layer, featuring the Chinese Double Connection Knot and Button Knot, enhances the aesthetic structure. This double-layered relationship explores structural recursion and unity, with formal repetition creating a self-aware object.
