Sound sculpture by Wolfgang Georgsdorf (2011).
First exhibited in Vienna and then part of a travelling exhibition throughout 2011 on behalf of the UN-declared Year of the Forest. A red and a white billard ball chasing each other towed by clamps on rubber strings and bouncing over tuned logs, untriggered when visitors are approaching.
Material: tree trunks, iron billard sized table frame, tow lift, motion detector, 2 billard balls, electric motor.
Technical Support / Mechatronical Realisation: Stadtwerkstatt/Linz, Austria.
Thanks to Alfred Woegerbauer and Franz Xaver.
