+   The nadir rotations explained geometrically. The items on screen
+   are rotated so that their local vertical axis points to
+   the vanishing point (nadir) placed outside the screen.
+
+Interestingly, it appears in our experience 
+that the placement of the nadir should
+be an absolute *angle* below the center of the screen from
+the viewer's point of view, rather than related to the size
+of the screen.
+
 The benefit of the nadir view is not only the appearance
 but also it makes the different pieces of text on the screen
 visually more distinct from each other,
