“Gregorio Siem's work takes us by surprise with the faultless production of polychrome mobile structures that are assembled in a variety of surfaces and whose elements are transformed into different shapes depending on the action of the audience. Depending on who encounters the work and who feels the need to touch, manipulate, move and play play with it, the sculpture becomes a different piece from the initial creation. This appearance of perpetual renovation promotes constant change, shifting mathematical sets obsessively ordered by the artist inside a structured pattern of lines and colors, prevailing partners in each new form. This color display proves the most depurated technique of rigor, coherence and solidity. Siem’s basic premise at the moment of venturing into the creative process, when conceiving the construction and deconstruction of new codes, is based on everything that exists in the universe, and on how certain shapes remind us for example of the DNA and the human genome constitution, the fundamental definition of mankind.

Inside this condition of continuous metamorphosis, the transformation is produced from the codification to its shape, recreating new possibilities and maintaining the problem of change from its randomness and in analogy with reality itself, permeable from the ephemeral and from its changing condition. So it is that the resulting mutation is the reason for the work that by itself cannot happen, alienated to the contact with the other, who by its own impulse and will “rebuilds it”, giving it anew shape, as relative and temporal as the fundamental value that constitutes it. Siem undertakes an evolving journey with many multiple plastic possibilities, proposing to make the spectator aware of the changes on every existence in this infinite, mysterious and yet unknown universe.”
