Necker Cube Optical Illusion

First published in 1832 by Swiss crystallographer Louis Albert Necker, The Necker Cube is an ambiguous line drawing.

Is the blue face the front or back face of this cube?

Is the blue dot inside or outside the cube?

Ambiguous Optical Illusion

It is a wire-frame drawing of a cube in isometric perspective. This makes the picture ambiguous; it can be interpreted two different ways. When a person stares at the picture, it will often seem to flip back and forth between the two valid interpretations.

Anomalous Motion Optical Illusion

AKA Peripheral Drift Optical Illusion is characterized by anomalous motion that can be observed in peripheral vision.
Warning: This page contains some works of "anomalous motion illusion", which might make sensitive observers dizzy or sick. Should you feel dizzy, leave this page immediately.
The above is a serious warning that I borrowed from the master of anomalous optical illusions, Professor Akiyoshi Kitaoka, of Ritsumeikan University, Kyoto, Japan.

Professor Kitaoka wasn't the first to notice that certain images appear to move if viewed in your peripheral vision. But he has studied the effect and perfected the creation of these optical illusions.

The first anomalous motion optical illusion is one that I created.

purple nurple optical illusion
Sea Sickness
(Update: the web seems to have named this
"The Purple Nurple Optical Illusion")
Walter Anthony
(c)2012

Keep in mind that this is a static image. It is not animated in any way. but as your vision moves back and forth the center area seems to be moving toward the center (contracting) and the outer edges seem to be moving away (expanding) from the center. Also worth noting is that if you fixate on a point in the center and don't move your eyes this anomalous motion will stop.

The next optical illusion is by the professor himself. Take a look at these snakes, do they rotate? For an even more amazing experience click on the image. It should open in a new window and take up the entire screen. Remember this image is not animated.

Each snake appears to rotate.

Printer Alert----> If you have access to a color printer this illusion works on paper too! Print out a large version to amaze your family or friends.


Explanation----> Professor Kitaoka has provided a more detailed explanation of the peripheral drift illusion in PDF.


Finally the last example is from a friend, Herman Verwaal from Exloo, Netherlands. Since he has retired he has taken to creating optical illusions of all types. Here is one of his anomalous motion optical illusions. Notice the attempted motion this time is side to side (lateral).

Well there you have examples of three forms of anomalous motion optical illusions.

1. Expanding/Contracting
2. Rotational
3. Lateral

I love this visual oddity. We've seen this with craters on the moon and foot prints in the sand. The photographer has this to say about the photos.

"This is two copies of the exact same photo, rotated 180 degrees from each other.

Are the letters on the marker raised or imprinted?

Is the marker itself slightly concave or slightly convex? "

Color Contrast Optical Illusion

The below two cubes share some things in common. The creator of this optical illusion states the following.
"Despite the fundamental difference in the apparent colour of the 'blue' tiles on top of the left cube, and the 'yellow' tiles on the top of the right cube, all the tiles are in fact physically identical (grey in both cases)."
I'll take this one step further and let you know that the RGB value for all 11 squares mentioned is exactly the same R:136 G:136 B:136. The blue and yellow squares mentioned are the exact same color as the gray block to the right.

Dale Purves M.D.
R. Beau Lotto
(c)2012

But they are not the only tiles on these cubes that look different but are exactly the same. Can you spot the other tiles that look different but are actually the same exact color?



The truth is that the optical illusion for tiles numbered 1 are the result of color contrast and the optical illusion for tiles numbered 2 and 3 are the result of brightness contrast.

With that said you must have no doubts that what I'm stating as fact is true. What's that you say? You don't believe it? Ok, OK already, quiet down. I guess we will just have to take the steps needed to prove that I am correct.

Project: Proving all the 1, 2, or 3 tiles are respectively all the same color.

There are a few ways you can prove that the tiles are the same color.

Before we continue, right click on the top image and open it in a new window. Now you have an image to work with.

1) You can use a graphics program like Photoshop, Paint.Net, Gimp or the Colorzilla extension for Firefox browser.

My choice is Colorzilla w/Firefox. Using the eyedropper tool you can determine that the RGB values of the respective tiles are the same, for number 1 tiles the RGB value is R:136 G:136 B:136, number 2 tiles have a RGB value of R:182 G:159 B:14, and number 3 tiles have a RGB value of R:75 G:45 B:138.

Not good enough for you, heh? Still not ready to trust that the computer is correct or you don't have an eyedropper tool? Either way you can move on to step 2 or 3 below.

2) Cut out a cardboard mask.

By viewing patches of the squares without the surrounding context, you can remove the effect of the illusion. A piece of cardboard with holes created in the right spots will work as a mask for a computer screen or as a mask for a the printed illusion. Holding up this mask to the image on the screen or printed paper should be enough to convince you. But if you were like my daughter nothing but this next step would do.

3) Print the image and cut out the respective tiles.

WARNING: Do Not use any specialty scissors your mother or wife uses for any kind of crafts, IE. quilting or fabric scissors. Doing this can be hazardous to your short term happiness. When in doubt get permission to use the scissors first.

This is another way to isolate the patches from their surrounding context. Cut out each tile along the edges. Remove them. Hold them side by side. Overlap the cut out tiles. Yup they're the same color. No denying it now, is there?

Please note that I have heard that some printers have "enhancement" processing that increases the contrast of edges. This can cause the printed squares to have slightly different RGB values. I haven't run into one of these printers yet where the overlapped squares didn't look identical, but your mileage may vary.

4) Of course you could just go to the interactive demo that the creator has up on his site. He shows both the color contrast and brightness contrast illusions, plus a few more that will make you think twice about believing what you see.

Spiral Optical Illusion

Spiral Optical Illusion


Here is another spiral illusion - this time in Snail-o-vision! Interesting fact about this optical illusion, is that when people encounter it for the first time, based on their previous experience with illusions, they presume it has something to do with perpetual motion. At least that is what I presumed. I thought the only illusion happening here is “seemingly moving” spiral painted on our little snail’s shell, and not the best example of that type at all! If that was it, I wouldn’t be much excited, and would probably forward this photo directly to my recycle bin. But then I read the email that was companion to this submission. It said something like: “Is the snail shell really a spiral”? I looked at the shell more closely, The spiral is actually composed of many concentric circles. Very good!

Ponzo Optical Illusion

From Wikipedia, the free encyclopedia - The Ponzo illusion is an optical illusion that was first demonstrated by the Italian psychologist Mario Ponzo (1882-1960) in 1913. He suggested that the human mind judges an object's size based on its background. He showed this by drawing two identical lines across a pair of converging lines, similar to railway tracks. The upper line looks longer because we interpret the converging sides according to linear perspective as parallel lines receding into the distance. In this context, we interpret the upper line as though it were farther away, so we see it as longer – a farther object would have to be longer than a nearer one for both to produce retinal images of the same size.

Ponzo Optical Illusion

I had been waiting quite a while for a great image to provide the backdrop for this illusion. Railroad tracks and long stretches of highway had been used to death. When I saw this great photo by Nuno Leitao I realized the search was over.

The two red lines (or three if you move your mouse over the image) below are duplicates, they are the exact same size. Which image is more convincing the one with two lines or the one with three lines?

Here is another anomalous motion optical illusion created by Herman J. Verwaal. He expressed to me that this wasn't one of his favorites, but I absolutely love this illusion. It has multiple illusions incorporated in this image. First there is the illusion of depth. These tiles appear to be 3-D. Second he states that the center slowly rotates clockwise but I see the whole image attempting to tilt clockwise with the center even more pronounced.

Photograph Optical Illusions

There are many ways to create an optical illusion. Digitally manipulating a photograph using software such as Photoshop or Gimp creates convincing images, but like special effects in the movies you know they are fake.

There are ways to setup true photographic optical illusions without altering or "faking" the image. Take the following actual photo as an example.

So how do you think the photo "Chess Anyone?" was accomplished?

One key to photographic illusions is the fact that photos are 2 dimensional images of 3 dimensional objects. This means most photo illusions would fall apart if you saw them first hand. If you wish to see the Chess Anyone illusion from an angle that will reveal how it was accomplished place your mouse over the below reveal screen.

Muller-Lyer Optical Illusion

The Muller-Lyer illusion is a size constancy illusion. In this illusion, the red and the blue lines below are the same length, but due to the effects of the arrows the red line appears longer.

muller-lyer optical illusion
The red and blues lines are both 170 pixels long


The illusion has been well studied since it was described by German psychiatrist Franz Carl Muller-Lyer in 1889. However, there is no certain explanation for the apparent difference in the perception of the lengths.

muller-lyer optical illusion
Muller-Lyer
1889

Muller-Lyer attempted to explain the illusion he had discovered as follows: "the judgment not only takes the lines themselves, but also, unintentionally, some part of the space on either side."

One of the better explanations I've read comes in the form of a PDF file from Catherine Q. Howe and Dale Purves of the Center for Cognitive Neuroscience, Duke University.

Below is an amazingly strong illusion that combines both the Ponzo and Muller-Lyer optical illusions.


Source
The two red vertical lines are the same length.
Placing your pointer over the image will aid you in exposing this illusion
.

In the tickets image above the perspective of distance lends itself to the Ponzo optical illusion, the angles at the end of each line add to this the Muller-Lyer illusion, combined they create a very effective optical illusion.


Project: Create your own illusion. See how the following variations might effect the relative strength of this illusion.

Does changing the color of the background change the effect?
Does changing the color of the arrows change the effect?
Try changing the color of the equal lines,
is there any combination of colors that is stronger then the others?
Try fat lines. Try skinny lines. Does the thickness of the lines affect this illusion?
Does the distance from which you view the illusion change the illusion?

What can you conclude, if anything, about how we perceive things from this project?
