Gianni Sarcone (previously) is a creator of immersive visual experiences who won third prize in the 2017 Optical Illusion Contest with his brilliant “Dynamic Müller Lyer Illusion”, which demonstrated how line lengths appear to lengthen or shorten due to movement of arrows placed at the end of the lines.
Müller-Lyer’s illusion proves that a segment can visually appear longer or shorter depending on the sense of the arrow heads at its ends. In what consists of my variant? As shown in the animation, the red dot in the middle of the line is equidistant from the other two red dots, although the ends of the line visually appear to alternately stretch and shrink like a rubber band!
Sarcone also created a couple of mind-bending variants from the original, one showing how lines and arrows behave in a circle and another showing how they behave in a sinusoidal zig-zag pattern.

I'm biased here, but this is one of the strongest visual illusions I have ever seen.

Another version of this awesome illusion from @gsarcone . The lines don't move, just the arrowheads. pic.twitter.com/Jn0t5wh68s
