Devices such as shoji screens, curtains, and blinds mediate vision while allowing light to pass through. Through material and color, they regulate transparency and alter the way space is perceived. This work was created as an entry for the Shinjuku Art Competition (Space Design Division), a program within the Shinjuku Creators Festa. Within the given condition of a public lobby space, it attempts to obstruct vision using a completely colorless and transparent material, thereby reconfiguring the relationship between transmission and concealment. Though transparent, the surrounding scenery becomes subtly distorted, layered, and reorganized. What emerges is not a new image, but the condition of seeing itself. This disturbance of perception through transparency later became the point of departure for the exploration developed in Mirage Cube. A series of works investigating the boundary between the visible and the invisible begins here.
