The artwork begins when Flutter of Butterflies Beyond Borders enters the Layered Infinite Transparency space. When it ends, Flutter of Butterflies Beyond Borders leaves the space.

To the viewer, the other people who overlap with the flutter of butterflies exist in the world of the artwork, and when the viewer is seen by others as overlapping with the flutter of butterflies, they also exist in the space of the artwork.

Multiple viewpoints are placed in the space of the world of the artwork, and the space of the artwork around the viewpoints is cut out and flattened using Ultrasubjective Space. When this flat surface is then placed in the exhibition space in the same position relative to the viewpoints, the world of the artwork is superimposed on the exhibition space. The viewer's viewpoint is not fixed; their viewpoint can move freely not only left and right but also in the depth direction, allowing them to explore a physical perception that immerses their entire body in the world of the artwork as they walk freely in all directions. When the viewer sees other people overlapping with the work through the screen, for them it is equivalent to that person being present not only in the exhibition space but also in the space of the artwork, and the other people become a part of the work.
