Sabine Schäfer, Ulrich Singer: GREEN CODE

»GREEN CODE«, a collaboration between Sabine Schäfer and Ulrich Singer, is a permanent garden installation with sound in the Zoologischer Stadtgarten Karlsruhe. A metal plate in the form of a QR code lies on the ground, the arrangement of pixels draws the contours of a butterfly for the human eye: visitors can scan the code shown on the panel with smartphones which guides them to a website with regularly changing sound compositions. With a »microscopic view« Schäfer and Singer introduce the audience to the sound microcosm of insect voices. Grass grows in the gaps of the QR code and gradually covers the code completely; when mowed, the process starts all over again.

»GREEN CODE« was selected for the »Seasons of Media Arts« 2020 by ZKM | Karlsruhe.
