One of the things i found in this edition of Ars Electronica was the Klangwolke. Thousands of letters made by kids and families under a collective aim, as it is explained here http://www.aec.at/klangwolke/participate/
The voestalpine Klangwolke defines itself as a work by all, for all, and as such, it’s not going to take shape behind closed doors or in the ivory towers of the arts and sciences. This production is coming to be in open labs, apprenticeship workshops and music schools, and in people’s homes—kids’ rooms and work spaces, cellars and attics. The voestalpine Klangwolke is emerging wherever men and women have electrifying ideas and the energy to bring them to fruition.
