How is the sentence structure like the Necker cube?

When two lines cross, the picture does not show which is in front and which is behind. This makes the picture ambiguous; it can be interpreted two different ways.

What is the Necker cube in art?

Necker cube. The Necker cube is an optical illusion first published as a rhomboid in 1832 by Swiss crystallographer Louis Albert Necker. It is a simple wire-frame drawing of a cube with no visual cues as to its orientation, so it can be interpreted to have either the lower-left or the upper-right square as its front side.

Who was Louis Albert Necker?

Louis Albert Necker (1786-1861), a Swiss crystallographer and geographer. Look at the cube and think about where the front face of the cube is. Is it above or below the back face? Hover your cursor over the image and then remove it to highlight different faces of the cube that you might experience as being the front face.

How do vampires use the Necker cube?

How do you change the orientation of a Necker cube?

The orientation of the Necker cube can also be altered by shifting the observer’s point of view. When seen from apparent above, one face tends to be seen closer; and in contrast, when seen from a subjective viewpoint that is below, a different face comes to the fore.
