| Tetrahedron-centered perspective projection into 3D space, with nearest tetrahedron to the 4D viewpoint rendered in red, and the 4 surrounding octahedra in green. Cells lying on the far side of the polytope have been culled for clarity (although they can be discerned from the edge outlines). The rotation is only of the 3D projection image, in order to show its structure, not a rotation in 4D space. |

Famous quotes containing the word images:
“We picked each other from afar and knew
What hour of terror comes to test the soul,
And in that terror’s name obeyed the call,
And understood, what none have understood,
Those images that waken in the blood.”
—William Butler Yeats (1865–1939)
“Style a tablet at every noon time, Lady,
With bold images of a timid boy!”
—Allen Tate (1899–1979)
“Forgetfulness is necessary to remembrance. Ideas are retained by renovation of that impression which time is always wearing away, and which new images are striving to obliterate. If useless thoughts could be expelled from the mind, all the valuable parts of our knowledge would more frequently recur, and every recurrence would reinstate them in their former place.”
—Samuel Johnson (1709–1784)
