Illusion vs Reality

“Illusion, a derivative of reality, and vice versa.” – GS

For a little backstory… one day, a follower threw me a curveball: ‘What separates illusion from reality?’ I countered with a snap response: ‘What separates acceleration from speed?’

Perception in Motion: Illusion, Confusion, and Zen Insight

Many perceive the two 3D cross-like shapes as moving significantly, though they remain stationary!

The interplay of color shades (light/dark) on the edges and body of the cross-like wire frames creates the illusion of motion. The alternating shadings simulate “motion blur,” leading some researchers to attribute these illusory movements to delays in luminance processing, producing a signal that deceives the motion system and induces “kinetopsia” (motion perception)..

This brings to mind an anecdote: Two Zen monks debated a flag moved by the wind. One claimed, ‘The flag is moving…’ while the other countered, ‘The wind is moving!’ The monastery’s prior intervened, stating, ‘Not the wind, not the flag; the mind is moving…’

This short anecdote serves to explain that the concept and perception of motion is sometimes ambiguous.

Autokinetic Illusion

Immerse yourself in the mesmerizing experience as blue droplets seemingly sway gracefully, creating an illusion of gentle motion. The yellow horizontal lines contribute to a wave-like dance, enhancing the visual allure.

Hold On Tight” by Gianni A. Sarcone, crafted in 1997.

This op art piece embodies a peripheral drift illusion (PDI), wherein a sawtooth luminance grating in the visual periphery induces the illusion of movement.

Fascinatingly, studies by vision researchers reveal that the illusory motion activates brain regions akin to those triggered by actual movement.

Perceptual Puzzle

Size Distortion: The length and curvature of the blue curves A and B in the diagram are highly deceptive. However, the curves are congruent! This presents an intriguing variation of the Delboeuf illusion, wherein size judgment is distorted by peripheral context.

Is it possible to create objects out of nothing indefinitely?

Yes, but only with a geometric trick that combines perpetual motion and “magic”. All you need is a simple sheet of graph paper, which you’ll cut into three distinct pieces after going through a step-by-step procedure that allows you to create confetti indefinitely from nothing. The game can be played indefinitely in a cyclical fashion.

Illusory Geometry with Dice

Forced perspective is employed to craft a well-known object: the ‘tribar.’ Emerging from an “impossible catalog,” this object takes the form of a triangular structure, with square-section bars seamlessly joining at right angles. Constructing a tribar within three-dimensional space is an illusion; in Euclidean geometry, the sum of triangle angles always equals a flat angle.

Efforts to fashion a solid object resembling the tribar have met varying degrees of success. In this instance, our construction incorporates a deliberate ‘interruption’ that, when observed from a specific angle, creates the illusion of a complete triangle.

Consider fourteen dice. Sacrifice one by cutting to detach two faces (fig. a). Adjoin the remaining dice by gluing them together (fig. b), and affix the two faces of the truncated die onto the vertical stack of dice, as shown in fig. c.

Shortest Path?

If you had to choose the shortest path from point A to point B, crossing the four squares with sides of 1 unit, which path would you take: the red one or the green one?
