The idea of the line is used in PLAY as a device to work through the process of deconstructing the rules of the game and, hence, the use of the space. The line as the marker of game areas is a manifestation of the boundary — that which separates and delimits. Soon, it starts to emphasise linearity, traversing and connecting different layers of space: the stage, the backstage, the exterior, even the past. The marker line on the court becomes a transgressive line, a catalyst for numerous spatial and conceptual relations articulating different semantic levels. This is the line as a border, the line as a thread, the line as something that pierces or blurs, the line as temporal and sonic.
