“A Balloon for Linz” brings to light the acoustic response of specific locations in Linz. Together with the video, a series of exploratory walks were organized in the city of Linz. Participants were invited to pop balloons and listen to the acoustic architecture of the urban space. The project received an honorary mention at the Prix Ars Electronica 2011.
