The Mind-Bending Illusion That Will Leave You Speechless

🌀The portal spiral illusion involves spirals that appear to disappear into the top and generate new ones from the base.

🧠Your brain interprets rotational motion and vertical displacement in the spiral, leading to the illusion.

🌀The design and complexity of the spiral enhance the illusion, making it more difficult for the brain to determine the motion.

🌌The use of LEDs can further enhance the illusion and evoke memories of the game "Portal".

🎨The portal spiral illusion is a captivating example of optical art and design.

What is the name of this illusion?

—The illusion does not have an official name, but it is often referred to as the portal spiral illusion.

Who designed this illusion?

—The illusion was designed by Ada Cohen.

How does the illusion work?

—The illusion relies on the ambiguity between rotational motion and vertical displacement in the spiral, causing the brain to interpret the motion in different ways.

Does the illusion work with any spiral design?

—The illusion is more effective with a complex spiral design that makes it harder for the brain to determine the motion.

How can LEDs enhance the illusion?

—By using orange and blue LEDs, the illusion can be further enhanced and evoke memories of the game "Portal".
