Klangwolke ABC

The Klangwolken ABC was initiated as a social participation project, focusing on “character” in the age of networks, constituting one of the core programs at the voestalpine Klangwolke 2012. People create their own characters to interact with radio frequencies at the event – a huge galaxy of characters meeting at the Danube shoreline.

In Klangwolken ABC workshops, people construct their own alphabet characters and add a receiver and LED kit to link to the Klangwolken event itself. They select a character, assemble it, and personalize it in creative ways. Literally, every single person/character creates a unique character. The character created in the workshop is recorded in an image database and becomes part of the Klangwolke Font. In addition, the participants join CharakterBook, an online service that works like a micro-facebook, enabling people to browse for other characters created by other participants, to create messages ant to take social action. The individual characters created by the participants become words or messages through communicating and collaborating with each other. In the Klangwolken ABC, we collect messages as combinations of characters with characters – people with people.

On the day of the Klangwolke, Klangwolke ABC parades were held in Linz. In addition, a large group of letters gathered on the Danube at sunset. LEDs would light up in response to certain sounds or radio signals for individual letters or messages. The Klangwolke ABC not only expresses the personality of the letter constructors, it also leads to concrete actions by those involved who jointly shape the here and now.

Another project realized for the 2012 Klangwolke was the quadcopter swarm, so-called spaxels.
