The outline of people’s figures, the side view from head to torso, is cut out of wooden boards. The shapes were modeled after real people. Each outline is cut out in a different posture, and each board is made to stand up in space by fitting the corresponding person into it. When the person is inside the board, the work is a “performance,” but when they are not inside, the work is composed as a “three-dimensional object.” While the person is inside the board, they close their eyes, keep their bodies still, and focus on being in the board. Throughout the direct intervention in the space by the presence/absence of the figures, the heterogeneity, or non-physicality hidden in the body, is shown on the relationship with the board.
