Description Presented here is a vast gallery of many different forms of Optical Illusions. Whether these optical illusions are conveyed through fractals, photographs, architecture, art, or old fashioned pen and ink, they are bound to remind you that "seeing is not believing."

Caution!!!! Some of the optical illusions on this blog may cause dizziness or possibly epileptic seizures. The latter happens when the brain can't handle the conflicting information from your two eyes. If you start feeling unwell when using this website, immediately cover one eye with your hand and then leave the page. Do not close your eyes because that can make the attack worse.

Dice on Steps Optical Illusion

Dave Barlow created this illusion and frames it like this,

"The picture shows exactly the same model with two dice set upon it, from opposite viewpoints. The person with the uppermost view swears that the dark die is higher than the light one. The person with the lower view is certain that his friend is seeing things, because clearly, the lighter die is higher than the dark one.

Who is right?"

Basically, I doubt it's the same model. It seems to me that the fun of these illusions is that they are presented to us - on the computer screen - as 2D representations of a 3D reality. But that also sometimes makes it difficult to see what they're on about. As in this case.

Without a doubt this is the exact same model taken from different viewpoints.

OK for those who have come this far the secret of this model is that it is flat. Yup flat, the whole thing might be half an inch thick but there are no stairs that go up and down.

Well, what happened here is, on the second picture, the "object" has been rotated 180 degrees. As a result, the ascending stairs have now become descending. The dices have shifted their position from one side of the plane to another. Two pictures were taken from completely two different settings.

Is this an optical illusion or a riddle? I think it is a "seemingly-illusive" picture-riddle with a claim to contest.

The dice are in the exact same positions in both pictures. The model doesn't change, only the angle from which the photo is taken.
