ANNUN(暗雲)At GASBON METABOLISM, Yamanashi, Japan (April 25–May 25, 2025), Shinji Wakasa collaborated with the jewelry brand :CAFCA on ANNUN / Foam, Fluid, an immersive installation combining sound, live projection, and sculptural display. Centered on the fragile formation of soap bubbles and their magnified projection, the work explored transience, memory, absence, and the unstable boundary between the ephemeral and the monumental. Wakasa created the sound installation, shaping the space as a contemplative field of resonance and impermanence.
