Professor Akiyoshi Kitaoka, Faculty of Comprehensive Psychology at Ritsumeikan University, creates some of the best motion illusions out there. As such, he has been featured on An Optical Illusion on many occasions. One of his newer illusions, Moving Snakes, is presented below.

What do you see? Are the purple, black, green, and yellow snakes slithering in different directions? Notice how three of the snakes seem to be moving to the left while the other three are heading right. If you examine the sequence of the coloring, you’ll see that the position of the colors affect which direction the snakes appear to move.

When the sequence is purple and green on the left and black and yellow on the right, the snake seems to move left. When these color combinations are reverse, the snake seems to move right. If you find studying the colors in this illusion interesting, consider the opportunity to earn your high school diploma online at Northgate Academy.

Delboeuf Illusion

Brad — Fri, 05 Feb 2021 21:37:00 +0000

Research has shown that presenting a food portion in a smaller bowl creates the illusion of a larger portion. Conversely, presenting the foot in a larger bowl creates the illusion of a smaller portion. The quantity of the food remains the same. This phenomenon is known as the Delboeuf illusion.

This illusion forces your mind make a judgement about the relative size of an object (i.e., the cereal presented above). A study from 2005 suggests that this illusion works in a fashion similar to the Ebbinghaus illusion.

The illusion gets its name from Joseph Remi Leopold Delboeuf who created it in 1865. Delboeuf was a Belgian philosopher, mathematician, hypnotist, psychologist, and psychophysicist. A busy man indeed!

Another example, in its most simplest form, is presented below:

The Dual Axis Illusion appears to defy logic. It was created by Frank Force and beat out many great optical illusions to claim first place at the 2019 Best Illusion of the Year Contest.

The spinning shape seems to rotate around both a horizontal and vertical axis simultaneously. To add to the confusion, the direction of the rotation is also ambiguous. The video walks through a few different tricks to change your opinion as the shape continues to rotate and rotate.

Frank has worked in the games industry for more than twenty years. He has also released over 50 games with the source code available. He has worked with many developers including Rooster Teeth Games, Certain Affinity, LightBox, Volition, Midway Games, and Hypnotix. More information about Frank can be found on his website – Killed By a Pixel.

All Is Vanity by Charles Allan Gilbert

Brad — Thu, 04 Feb 2021 20:56:27 +0000

This optical illusion is an “oldie but a goodie” and is worth having another look at. The drawing, entitled All Is Vanity, was created by Charles Allan Gilbert. Gilbert was a prominent American illustrator whose work appeared in magazines, books, posters, and calendars. Later, he went on to work on animated films and also served as a camouflage artist during World War I.

This drawing is no doubt his most famous and is the one that he is typically remembered for. The drawing itself is a double image that can be seen in one of two interpretations. The first is that of a woman in a dress looking at herself in a mirror. The second is that of a human skull. The skull becomes even more noticeable if the picture is viewed from afar.

The title of the drawing is an obvious pun. The woman is sitting at a vanity (a dressing table) looking in the mirror. As she seems to be admiring her beauty, she is also basking in her own appearance demonstrating her own vanity.

Charlie Chaplin Optical Illusion

Brad — Thu, 04 Feb 2021 20:33:06 +0000

Charlie Chaplin made his name as a comic actor in silent films During his illustrious career, he directed eleven films including hits such as City Lights, The Gold Rush, Modern Times, The Great Dictator, and The Kid.

In this video, Charlie changes it up a bit and plays the role of an optical illusion. A hollow mask of his face slowly rotates around in a circle. The hollow part of the mask appears to form a convex face that rotates in the opposite direction.

As soon as the features appear on the concave part of the mask, your brain assumes that they are convex and forms the new face with the nose sticking out.

Our minds have been trained to recognize faces since we were children. So when we see the features (eyes, nose, and mouth) on the hollow portion of the mask, our brain assumes that it must be like other faces that we have seen and must therefore be convex.

Duck Rabbit Illusion

I just searched through the archives, and I cannot believe that the famous duck rabbit optical illusion has not been featured in the past. You’ve probably already seen this image, but it is worth another look because of its powerful simplicity.

Do you see a duck or a rabbit? Can you find both? The animal that you first see when you view this illusion may be a reflection of your own personality.

Because this illusion is such a classic, in 2009 a book was published called Duck! Rabbit! Authored by Amy Krouse Rosenthal and Tom Lichtenheld, the book is described as “…a smart, simple story that will make readers of all ages eager to take a side…” The book is a New York Times Bestseller and is available on Amazon here.

The popularity of this title is a testament to the staying-power of simple optical illusions. Of course, the authors deserve some credit here too for making it into a compelling story for children.

So the only question is… do you see a duck or a rabbit?
