Mateo Amaral is a multidisciplinary artist who develops his work using techniques such as drawing and painting, three-dimensional digital animation, distortion of video through software errors, exploration of audiovisual noise and production of electronic music. His research leads him to experiment with hypnotic audiovisual landscapes, drawing parallels between primitive digital aesthetics and the individual construction of the reality model. All his work revolves around "Una piedra negra", an expanded feature film project that produces short films, paintings, installations, virtual reality pieces and live audiovisual performances.

In 2016, he was the winner of the first Virtual Reality award within the ITAU prize for visual arts. In addition to his individual work, he formed the artistic collective Oligatega with which in 2003 he was a scholar in the program of workshops dictated by Guillermo Kuitca and participated in the work clinics of Diana Aisemberg. His work was exhibited at the Cultural Center of Belgrade (Serbia), Museum of Modern Art of Buenos Aires, at the festivals ArtFutura, Mutek, Sonar, Robot and Trimarchi, at Artists' Television Access (San Francisco, USA), Museum of Contemporary Art of Castilla y LeÛn (Spain), Art Basel (Switzerland) and the Experimentation Center of the Teatro ColÛn (Buenos Aires).
