The flow is influenced by the shape of the space and the presence of people, and it continuously interacts with and transforms with all the other flows in the artwork space. The flow is considered as a continuum of countless interacting particles, and lines are drawn by the trajectories of these particles. 

This artwork is not an illusion of space; the artwork space exists as it is in the space where people's bodies are, and the space is covered by the flow.

Images created by camera lenses and perspective represent the illusion of space, depicting a three-dimensional space on a two-dimensional plane. In this illusion, the three-dimensional space appears beyond the two-dimensional surface, and the viewers are in a different space from the three-dimensional space, making the two-dimensional plane a boundary. With this, the viewpoint is fixed, and the viewer’s body is absent. In contrast, this artwork does not create an illusion of space. Instead, the space of the artwork directly exists in the same space as the viewer's body. Walls and floors do not act as a boundary between the person and the space of the artwork, but rather, the space of the artwork integrates with the space in which the viewer's body exists. The viewpoint is not fixed, and their body remains free.
