This torus always faces the front, whether observed from the side or from below. The torus that you're looking at facing forward is simultaneously facing forward to another viewer standing elsewhere.

A torus that constantly appears to face front, no matter the angle from which it is observed from, does not exist in the real world.

This torus exists as a torus within the viewer's cognitive world. We refer to such artworks that don’t exist in the physical world but exists in the perceived world as Cognitive Sculpture. When it exists within perception, it is considered to exist.

“The existence of an ocean vortex is made up of the same water, both inside and outside. There is no material difference. Despite this, why do we feel a sense of existence in the vortices of the ocean?”

The difference between the inside and outside of an entity, such as a vortex, lies in the order, not the material.

Even if components of an artwork are temporally and spatially dispersed, when order is established within a part, that part and its components can be recognized as a singular existence transcending space-time.

A sculpture composed of an order formed by a collection of light that flows continuously from the outside to the inside and from the inside to the outside.

The artworks Light Vortex, Obverse and Reverse, Light Sculpture - Flow, and Absolute Front Torus, can be seen in the same space.
