A photo report from Zagreb introduces a museum where visitors can continue other people's artwork. A visitor can begin a piece or pick up one already in progress. The next person may develop it further, while someone else can eventually bring it to completion. The resulting work may therefore have several contributors rather than a single identifiable author. M. Lukjanov said an artwork does not need to be finished to have meaning within this setting. Participation forms part of the creative process instead of being separated from the act of viewing. Each visitor's decision changes what the next person inherits and develops. The museum's appeal rests on that chain of shared authorship, with unfinished work treated as an invitation rather than a failure.
