Geometric patterns that appear to distort or defy logic are examples of common optical illusions.
These shapes can create illusions of movement or three-dimensional effects on flat surfaces according to their spatial properties.
An illustration of this is the well-known Escher staircase, which defies the rules
of physics by appearing to have stairs that both ascend and fall at the same interval.
The subtleties of how our brains absorb visual information are brought to light by these illusions,
which also serve to illustrate the disparity between what our eyes see and how our minds interpret it.
Through the study of optical illusions, researchers are able to obtain a better understanding of the mechanisms that underlie visual perception.
