Kim Yun Shin’s seminal series "Add Two Add One Divide Two Divide One" is inspired by her interests in architecture and philosophy. Kim was specifically inspired by the wooden fittings of hanoks (traditional Korean houses), which utilize an architectural technique called “Gyeolgu-beop” where, instead of using nails, the components are fitted together by carving slots, creating interlocking joints or grooves. The title "Add Two Add One Divide Two Divide One" also represents what became a foundational and defining philosophy throughout Kim’s work. This phrase signifies a phenomenon in which two disparate entities interact to become one, then divide to become two again, with each becoming its own entity — mirroring the Gyeolgu-beop technique. Fusing formal techniques and spiritual philosophy, for the artist, this phenomenon speaks towards her spiritual orientation towards artmaking, where in the process of creating the artist and the art become one, and eventually are separated into their own entities upon completion–“I go through the process of immersion where nature, the material, and I become one.”
