Federico Díaz (* 1971), a visual activist of  Czech-Argentinean descent, lives and works in Prague. Since the 1990s he has used new media to reveal immaterial aspects of everyday reality of our natural environment which are elusive through primary human senses. Díaz’s work is typified by the language of algorithmically-generated art and systems art, increasingly more intense channels of direct communication with the viewer and the ability to follow his basic creative premise, which says that art is created without the touch of the human hand. He uses media and technologies as a socio-political catalyst of social changes.
