Eight Gate

Filed under: General,Geometry — Tags: , — m759 @ 12:00 PM

From a Huffington Post  discussion of aesthetics by Colm Mulcahy
of Spelman College, Atlanta:

“The image below on the left… is… overly simplistic, and lacks reality:

IMAGE - Two eightfold cubes- axonometric view on left, perspective view on right

It’s all a matter of perspective: the problem here is that opposite sides
of the cube, which are parallel in real life, actually look parallel in the
left image! The image on the right is better….”
