Open Lab Narrative Systems was created in October 2016 at the Faculty of Graphic Arts of the Academy of Fine Arts in Warsaw. Initially, Systems were optional classes for students of the Faculty, but they quickly evolved towards open research workshop. The curriculum is oriented on the direction and form of narration in audiovisual projects. The first implementation of the Narrative Systems is the SIGN SYSTEM OF AUDIOVISUAL LANGUAGE. Its goal is to build graphic representations of concepts describing audiovisual structures.
