👀Look at these optical Illusions! 👀

Nice discussion about optical illusions @Elsa, and thanks for the tag @Diamond Lim. Here are my answers to these puzzles.

The left picture shows both a person and a waterfall. The right picture is supposed to be a farm, but it also shows someone's face, with the house windows being its eyes, and a mustache near the lambs.

For the second puzzle, the left picture someone is holding an umbrella under the Eiffel Tower. It also somewhat looks like a big face. The picture on the right shows two things: someone's half-face looking at you OR someone’s full face looking at the right.

And here are some optical illusion examples:

Everyone see things differently. You can say that the picture above represents two fish in a black sea, or these two fish are actually eyes of a person.

Here's some information on optical illusions:

An optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual percept that arguably appears to differ from reality. Illusions come in a wide variety; their categorization is difficult because the underlying cause is often not clear but a classification proposed by Richard Gregory is useful as an orientation. According to that, there are three main classes: physical, physiological, and cognitive illusions, and in each class there are four kinds: Ambiguities, distortions, paradoxes, and fictions. A classical example for a physical distortion would be the apparent bending of a stick half immerged in water; an example for a physiological paradox is the motion aftereffect (where, despite movement, position remains unchanged). An example for a physiological fiction is an afterimage. Physical illusions are caused by the physical environment, e.g. by the optical properties of water. Physiological illusions arise in the eye or the visual pathway, e.g. from the effects of excessive stimulation of a specific receptor type. Cognitive visual illusions are the result of unconscious inferences and are perhaps those most widely known.
