Two hundred and seventy white garbage bags hang like ghosts in the columned hall of Vienna, Austria’s Museum für agewandte Kunst (MAK) for the exhibition Sagmeister & Walsh: Beauty. The piece is by Nils Völker, and is titled after the number of bags present in the installation. Over 1000 precisely installed fans and 45 circuit boards keep their movement on track, helping to rhythmically inflate and deflate the hanging plastic objects.
