Held annually in September in Linz, Ars Electronica is one of the world's most important festivals for digital art, technology, and culture. The festival takes over the city with exhibitions, performances, symposia, and the spectacular Klangwolke (Cloud of Sound) — an outdoor multimedia spectacle along the Danube involving hundreds of performers. The Prix Ars Electronica is the most coveted award in digital and interactive art globally.
