The performance «Marking the space» was made during my stay at UNIDEE - University of Ideas («The rituals of the contemporary» program). By attaching a thin red thread to the elements of the interior, I consistently limited the space where the audience was, forcing them to walk backwards and move in the direction I chose. How do the mechanisms for controlling the space and movements of people, which the executive authority uses, work? Will someone dare to break the thread, to overstep the illusory border, or will everyone follow the rules?
