Steli works in the field of geometric abstraction, which he accepts as a universal language, easy to understand and which could be translated and interpreted in different ways.
He uses the color as an instrument, not as a mean of expression. The color is both a form and a content. The form follows the process as the artist builds consistent layers of lines, intertwining and affecting each other to achieve an impact with color, shape and rhythm. The artist is trying to create a sense of space and movement, of a self-organizing system, which in turn finds expression in the intangible energy that underlies our existence.
