Do you see a donkey?

Do you see a duck, or a rabbit?

Do you see a duck, or a rabbit?

Do you see a face? Look carefully!

Do you see a woman holding a glass? Or something else?

Do you see an eskimo, or an Indian?

Do you see just a horse?

Do you see spots in between squares?

Do you think you are going down the stairs?

Does the flowerpot face upward or the side wall?

Does the lower corner of the square look bent?

Doesn't expand on one end.

Doesn't look like it is going to be closed.

Doesn't look very delicious.

Doesn't look very delicious.

Don Quixote, or a windmill?

Don't look for an illusion. It is here because of its beauty.

Don't move your eyes from ghost for 45 seconds. After that, look at the castle.

Don't pick your nose.

Don't you think it is getting domelike? (The image is Copyright A. Kitaoka)
