Optical illusions have a long history of use as a medium for psychological and artistic experimentation.
These illusions demonstrate how our minds construct meaning from visual information received, highlighting the complex interplay between our eyes and brain.
The ambiguous figure-ground illusion is a famous example of this phenomenon, in which the observer's brain switches between seeing two distinct pictures.
Another interesting thing about optical illusions is that they show how subjective our perceptions can be.
The subjective nature of visual perception is highlighted by the fact that one's perception may differ greatly from another's understanding.
