Peace 3D Stereogram Optical Illusion Video

Stereo, Video 6 September 2023 No Comments Yet - Share Your Thoughts

3D stereograms, made popular in the 1990s, reveal a hidden image upon staring at the pattern. Some people claim that they have never been able to see these, but almost everyone without an eye problem can in fact see them. The trick is to relax your eyes and let the image come to you. Patience is also recommended when trying to view them for the first time.

This stereogram video features a static hidden image with several pattern changes. Once you bring the hidden image into focus, it will remain there even as a new pattern replaces the old one.

Can you tell what it is?

Moving Snakes Motion Illusion

Motion 2 March 2021 No Comments Yet - Share Your Thoughts

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

Estimation 5 February 2021 No Comments Yet - Share Your Thoughts

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!

Dual Axis Illusion

Ambiguous, Video 4 February 2021 No Comments Yet - Share Your Thoughts

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

Hidden Objects, Skull 4 February 2021 No Comments Yet - Share Your Thoughts

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

Ambiguous, Video 4 February 2021 1 Comment

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.
