A horizontal length of dried wall paint runs along the walls, cutting passages and lines of sight as it describes a path connecting one end of the room with the other.
Then, a sudden turn – it veers off from the wall, striving towards the center of the room, then back again, turning itself inside out, before resuming its track along the wall. But only briefly. Soon enough there’s another turning point changing the direction, before it all ends, just as abruptly as it started.
