Whose Forest, Whose World is a publication catalogue design project for an ecological exhibition exploring the equal coexistence of human and non-human beings. The cover directly manifests the central concept, "beings drawn in atoms." The catalogue establishes an intricate editorial system reflecting the atmosphere of the exhibition space and the material characteristics of the featured works. Based on this framework, the book format was tailored to accommodate the prominent share of photography and painting in the exhibition, arranging plates in alignment with the physical positioning and proportions of the artworks installed in the gallery.
