This work reimagines the traditional Korean byeongpung, a folding screen of hanji and fabric, used to divide space and display art. Created for the Architect’s Furniture Design Exhibition at the Lock Museum in Seoul, it is crafted from a single sheet of perforated stainless steel. The punctured dotted lines act as hinges, bending into curves that evoke a Yin–Yang motif, with no fixed front or back. As it folds, light filters through the perforations, transforming the surrounding space into a shifting, luminous field. Now in the collection of the National Museum of Modern and Contemporary Art, Gwacheon.
