The artwork begins when Flutter of Butterflies Beyond Borders enters the Frozen Transparency space. It ends when, Flutter of Butterflies Beyond Borders leaves.

Real space overlaps with that of the artwork world, while the artwork incorporates real space, the boundary between the artwork and real space is ambiguous and one.

When the viewer is in the artwork space, the artwork space as seen by other people from outside the artwork is the same as that seen by the viewer from within the artwork space.

In other words, when the viewer looks at the world of the artwork, or when the viewer is seen by others, both the real space of the artwork and the viewer exist within the artwork world.
