We do not perceive the world we see, we see the world we perceive.

A sphere of light, there is no material, such as glass, on the surface of this sphere; the sphere is made only of light. There is no material surface boundary, and the perception of the boundary with your body is ambiguous. Likewise, there is no material surface boundary in the window opening.  

In reality, light cannot solidify into a spherical mass in the universe. Therefore, this sphere does not physically exist.

This is a Cognitive Sculpture that appears only in the human world of perception. The materials are light and the environment. And the subject of its creation is the viewer's own body and perception.

The sphere cannot exist on its own - its existence is a phenomenon created in relation to its environment. The phenomenon created by the environment is shaped for the first time by the dynamic body and perception of the viewer, becoming a sculpture in their cognitive world.

The artwork explores the possibility of a new form of existence distinct from material existences, and questions the very nature of existence.
