What is computational art? How does it involve us in unprecedented aesthetic relationships, making us part of works and even transfor­ming them? This book looks at how computation causes an ontolo­gical shift that turns dynamics, causality, and cognition into central components of art, artistic practices, and aesthetics. Computational art is more conceptual than perceptual; it is performative, experien­tial, situated, experimental, creative, and intersubjective. Computa­tional art is unstable, generative, and irreducible, and as such, it has unique transformative potential. 'Art and Computatio'n calls attention to computation as a tool, material, medium, and art. It calls for de­veloping aesthetic experiences predicated on our engagement with and attunement to the computational core of art.
