What is computational art? How does it involve us in unprecedented aesthetic relationships, making us part of works and even transfor ming them? This book looks at how computation causes an ontolo gical 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, experien tial, situated, experimental, creative, and intersubjective. Computa tional 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 de veloping aesthetic experiences predicated on our engagement with and attunement to the computational core of art.
