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.

Painting-in-Progess Optical illusion

This painting-in-progress blends into the landscape well. This photo has not been manipulated in any fashion.

When I first saw this photo I thought the whole thing was a painting due to the shadow pattern created on his face by the hat. Strange how even with the simplest things your eyes can play tricks on you.

Raised or Indented?

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? "
What do you think?

Paris - Rome Sign Optical Illusion

Here is another excellent optical illusion from Sarcone & Waeber. Look at the two sign poles below, Sarcone & Waeber ask one question, "are the poles straight and parallel?"

What do you think?

Pull out a ruler and measure the gap at the top and bottom and you'll prove to yourself that they are in fact parallel.

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?

Neon Heart Optical Illusion

Here is an excellent neon color spreading optical illusion from Sarcone & Waeber. Every yellowish square below is the exact same color, yet most of us will see a pale orange neon heart. If you can't see it step back from your monitor and look again.

Keep in mind that the orange color doesn't exist as pixels on the screen only in your mind's eye. Each square below has the exact same yellow background.

Rotating Quadrants Optical Illusion

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.

Montmartre Sinking Optical Illusion

Hugo, the photographer says he took this amazing picture,

"from the stairs leading to the Sacré Coeur on a Sunday: it was packed with tourists, all shooting the monument, and they were looking at me really weird, taking this big piece of lawn ! lol"
What could have caused this building in Paris to sink? A massive sink hole? A broken water main? Perhaps very large gophers?
