Whether they make up an SMS, an e-mail, a Facebook post or a handwritten missive, letters are the elementary particles of our communication. As indispensible protagonists in the history of the networking of the world, they’re also an essential part of the Cloud in the Web. The manifold shapes and assorted colors of the thousands of letters that participants here in Linz and worldwide on the internet have been creating for the 2012 voestalpine Klangwolke reflect these people’s individual personalities.

The deadline for adding another letter to this huge alphabet isn’t until just about the last minute. You can craft yours at the ABC Workshop, in the comfort of your own home, or at an OTELO open technology lab in Gmunden, Vöcklabruck and Kremstal. Components are available free of charge at all ABC Check-in Stations, where you can also register your finished letter and get it equipped with a radio receiver.
