In designing of the ticket hall and the corridors of the metro we applied the graphic trick, when some kind of geometric figure is imagined on several surfaces, in our case on the ceiling, floors and walls; moreover it's "correct" form can be read only from one point, but with displacement it crumbles to pieces. The big orange-yellow circle in the end of the corridor and ticket hall determines the direction and also works on the conceived station image as a space full of light.
