Ollusion

Ollusion is a term used to describe a specific type of visual illusion. It typically refers to an optical phenomenon where a viewer perceives a static image as if it were moving. This effect is often achieved through the careful arrangement of shapes, colors, and patterns that create a sense of dynamism, even though the image itself is not changing. Artists and designers utilize ollusion to evoke feelings of energy, depth, or instability within their work. The perception of movement in an ollusion is subjective and can vary from person to person, influenced by factors such as attention, gaze direction, and even individual neurological processing. While not a scientific term with a precise definition, ollusion is widely understood within the art and design communities to represent a deliberate manipulation of visual perception to simulate motion. Examples can be found in op art, kinetic art, and certain digital graphics. The psychological basis for ollusion is complex, often involving the brain's interpretation of visual cues and its tendency to find patterns and movement even where none exist.
