The exhibition encompasses twenty years of Polish art after liberalization with works of several artists. Curator asked for an object binding together both practical dimension of a bookshelf for a library opened spacially for exhibition’s occasion and a quality of an art object. Finally the bookshelf adresses the issue of evolving society with a structure increasingly complicating itself, depicted by German sociologist/philosopher Peter Sloterdijk with a simple figure of a foam in his trilogy „Die Sphaere”. A five-meter long net of pvc stripes changes it’s geometry every sixty seconds moved by an electrical engine placed above a steel frame that handles the whole structure causing astonishment, shock and hopefully reflection to unprepared library’s visitors.
