0 – 255 is an interactive web application that reflects on the notion of computation and the effects of code’s actualisation process. This project explores the role and meaning of human performance in the enactment of algorithmic artworks as performative aesthetic events. It proposes the audience to experience and perceive its expressive potential in procedurally reversing the 256 rules of one-dimensional cellular automata. Just like in an irreducible computation, the only way for the audience to work out how the system will behave is essentially to perform its computation along with the machine
