The impossible trident is a three-pronged impossible shape resembling a trident.
It is usually depicted as a three-pronged fork with each prong appearing to be a continuation of the next, creating an impossible shape.

How does the Impossible Trident Illusion work?
The “impossible trident” works by manipulating the viewer’s perception of depth and angles. The angles of the prongs are carefully designed so that they appear to be connected in a way that violates the rules of spatial relationships. This creates an illusion of an impossible object that is difficult for the brain to process.
The brain relies on cues such as relative size, shadow, and perspective to perceive depth and understand spatial relationships. In the case of the impossible trident, the artist manipulates these cues to create an image that appears to be impossible.
It is similar to the Penrose triangle, but the Penrose triangle is a 2D representation of an impossible object, whereas the impossible trident is a 3D representation.

Illusions like the Impossible Trident Illusion
Paradox illusions are a type of optical illusion that involve images that appear to be self-contradictory or impossible. They typically involve the manipulation of visual cues such as size, shape, movement, and depth perception to create an image that appears to be impossible or defies our understanding of the physical world.
In general, these illusions work by exploiting the way the visual system processes information. The brain relies on certain cues, such as perspective, shading, and texture, to infer the 3D structure of an object. When these cues are manipulated in a certain way, the brain can be fooled into perceiving an impossible or self-contradictory image.
Some related illusions include the following:
The Rubin vase, also known as the Rubin face or the figure-ground vase, is a famous optical illusion in which the image of a vase can also be perceived as two faces in profile looking at each other.
The duck-rabbit illusion is an optical illusion that is an image that can be perceived as either a duck or a rabbit depending on how the viewer looks at it.
The Necker cube is an optical illusion that features a simple wireframe drawing of a cube. The cube appears to switch back and forth between two different orientations.
The My Wife and My Mother-in-Law illusion is an optical illusion with an image of a young woman’s face that can also be perceived as an older woman’s face.
The Schröder Staircase is an optical illusion that features a drawing of a staircase. The staircase appears to be either ascending or descending, depending on how the brain interprets the angles of the lines.
The impossible cube is an optical illusion that depicts a three-dimensional object that is physically impossible to construct.
The Penrose triangle, also known as the Penrose tribar, is an optical illusion that depicts a three-dimensional object that is physically impossible to construct.
The spinning dancer illusion is a visual illusion that depicts a silhouette of a dancer spinning clockwise or counterclockwise. The direction of the dancer’s spin can appear to change depending on the viewer’s perception
The Monroe-Einstein illusion works by playing with the viewer’s expectations about the relationships between the features of the faces and the viewer’s sense of facial proportions.
Discovery of the Impossible Trident Illusion
The impossible trident it is a common variation of the impossible figures and impossible objects, which were popularized by the artist and mathematician Roger Penrose in the 1950s and 60s. He created a famous impossible object called the Penrose triangle, which is a 2D representation of an impossible object.
Impossible figures and impossible objects have been used in art and graphic design for decades, and it is likely that the impossible trident was created by an artist or designer who was inspired by Penrose’s work and created a variation of it.
