The Curtain Wall is conceived as one of a collection of elements of architecture that are each intertwined with their specific representational media. The Curtain Wall is generated with the help of a simulation that prioritizes appearance. Taken as a whole—which the viewer must do because Curtain Wall is smooth and contiguous with no noticeable seams—it is a contradiction. On one side it is read as firm and thick. On the other side it is flowing and thin, literally flapping in the wind. On this side, gravity wins. A frozen curtain is like a corpse. But as an animation, it comes alive.
