Julian Rohrhuber and Dave Griffiths are based in Düsseldorf and Penryn, respectively. They have both helped define the live-coding field through the software and practice they have developed, and now often work together on diverse projects. For Thinking Out Loud, Rohrhuber and Griffiths contribute their collaborative work Inca Telefax: Listening to Pre-Columbian administration without understanding a word. The piece is an occasionally broadcasting three-channel sound installation of algorithmically-generated sounds with accompanying images, pixelquipu, on permanent display, which derive their structure from Pre-Columbian quipu. Quipu, sometimes known as ‘talking knots’, took the form of necklace-shaped, coloured, spun and knotted threads which were used for many different, and partly unknown, administrative and scientific tasks. Inca Telefax creates an aural insight into quipu, allowing for an abstracted, contemplative encounter with an ancient form of data collection.
