The DodekaOTTO is a 20 channel sound sculpture based on the OTTOsonics project, which is comprised of a lightweight aluminum structure in the form of a dodecahedron. This open hardware platform has been designed at the Tangible Music Lab in order to provide a mobile environment for the realization of interactive multichannel installations. Its minimalist design consists of 30 aluminum tubes, which are structurally held together by 20 digitally designed aluminum plates integrating standard OTTOsonics speakers.
Currently there already exist five DodekaOTTO installations at the Tangible Music Lab in Linz, at the Alter Bauhof in Ottensheim, at HEKA in Koper/Slovenia, at the Ionian University at Corfu/Greece and at USJ Macau in China. You can freely download all necessary files for the structure, which are available under the CC-BY-NC-SA lisense, referencing the Tangible Music Lab, University of Arts Linz, Austria.
