There are a number of interesting visual phenomena known as optical illusions.
These phenomena challenge the way in which our brains perceive images by playing tricks on our perception.
These illusions take advantage of the complex workings of our visual system.
One type that is frequently encountered is the ambiguous figure, which occurs
when the same visual input can be interpreted in a number of different ways, resulting in a dynamic shift in perception.
Another fascinating illusion is the motion aftereffect, which occurs when a person
is exposed to a moving stimulus for an extended period of time and then experiences the sensation of motion in items that are not moving.
