The Necker Cube is an ambiguous line drawing. It can be interpreted two different ways. When a person stares at the picture, it will often seem to flip back and forth between the two valid interpretations. The Necker Cube is an optical illusion first published in 1832 by Swiss crystallographer Louis Albert Necker.

Like the paradox of the “half-empty/half-full glass of water” the Necker Cube shows how human perception is multi-stable. It can change and be changed–it can flip/flop.

This also shows why the cvs2bvs brain software is so powerful in the human perception system because it can change, or flip, perception from one stable state to another stable state–on command!

  1. I find these illusions very interesting and clearly they illustrate the fact that there is more than one view of a situation and that we have to try to be open to and recognise them all.

  2. As I stare at it, the image “flips” so I see it one way then the other. I have two questions. 1. I wonder what my brain is doing? 2. Can I make my brain change back and forth?

  3. it is quite interesting. our current view of any situation in life can become better based on some factors socio-cultural, belief system and time. time is usually pregnant with information that can change cvs 2 bvs.
