The best magic of all, is the magic that is real. (James TURRELL)
Tricks of the Eye
You can be fooled by your eyes, or you can fool your eyes to see things differently. Eitherway, this is an interesting exercise but it may take some effort so be patient.
The examples come from different sources, I have tried to give full credit where possible ( 21-00-photo-credits, 20-00-references, 19-00-bibliography ) but some of the examples are quite old really.

The Necker Cube
- by crystallographer Louis Albert NECKER
- 1932 Switzerland
- see also: im-possible.info for more explanation
The Necker cube is an optical illusion that was first published as a rhomboid in 1832 by Swiss crystallographer Louis Albert Necker.[1] It is a simple wire-frame, two dimensional 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.
The Necker cube is an ambiguous drawing.
Necker cube on the left, impossible cube on the right.
Each part of the picture is ambiguous by itself, yet the human visual system picks an interpretation of each part that makes the whole consistent.
