Masterclass with coloured threads was held at the festival in Teriberka town, Murmansk region. Participants moved around the space of the former barracks and leave traces, reflecting the trajectory of each of them. Creating a visual way to influence the further movement. Threads were found points of intersection, and clung to the formal and formal elements of architecture, and sometimes lined up in unexpected places, regardless of structure. The objectives of this art practices were the involvement of the viewer in the process of interaction with the abandoned space, and its development, a reflection on the theme of the possibility of refraction through the prism of modern games and historical processes.
