The symposium Expanded Animation was initiated in 2013 and offered a first approach to the expanded field of computer animation. In the meantime, it has become an established part of the Ars Electronica Animation Festival and the international competition Prix Ars Electronica Computer Animation. Every year under an overarching theme, the symposium has researched the field of technology and art, animation and aesthetics, investigated the collapsing boundaries in digital animation and explored positions and future trends. Much like the first conferences on computer animation at Ars Electronica in the 1980s, practice and theory are equally important. The richly illustrated publication Expanded Animation. The Anthology features contributions from speakers and artist positions from the past five years and presents an overview of the prize winners in Computer Animation.
