The corner of the room where the reader now finds himself appears at first glance to be nothing more than a practical intersection of two walls. Yet, it is nothing less than a crossroads of realities. Each wall carries its own flat world—two-dimensional, seemingly without depth. They meet at right angles, as if two universes, which would normally never touch, are forced into intimate contact here. The reader, that is, you, is standing precisely at this point. The article you are reading is not text on a screen or paper, but an invitation to experience the corner as a portal. Because what is a corner, anyway? It is not a wall, not a floor, not a ceiling. It is the place where divisions converge. A boundary that dissolves itself.
