The reading criterion of the work is the same as for the cylinder, with the difference that these artworks can form a continuous, infinite installation and appear differently. The active role of the viewer, who, immersed in the environment, becomes an integral part of the work itself, takes place not only through reflection, but through the alternation of geometric shapes, color and visual intertwining between the full, empty part and the mirrored part. Actor and viewer at the same time, the artist needs the viewer’s perception as the ultimate factor in the completion of the work, which only then is expressed in its uniqueness, never equal to itself. On the other hand, the artist has a new, more technical, scientific and objective means of communication. Expression through this new language causes the viewer to wonder about the differences between what it looks like and what it physically is, and about the changes that occur as a result of the change in point of view.
