#tweetscapes was originally commissioned as a pure sonification by German National Radio and was broadcast several times per week from 2011 to 2012. In January 2012, the web stream audiovisual version was additionally launched.

#tweetscapes came to life as a cooperation between HEAVYLISTENING, German National Radio, CITEC Bielefeld, and Sound Studies at University of the Arts Berlin. Here's the whole team involved in the making of the project.
