Unfortunately, the Ars Electronica did not get the permission to use this project during the voestalpine Klangwolke. Still, this blogpost offers some nice visuals.
Members of the Amanogawa-Team (Japanese-only website) have visited Linz to check out what their LED-Balls behave like in the Danube. 50 000 of those balls will be part of the performance of the voestalpine Klangwolke on September 1.
