2nd ESO. UNIT 4.2 Visual Perception. Optical Illusions, Escher

Optical Illusions are distortions or alterations in our perception. They act directly in our visual mechanism and our interpetation of what we see is different from the reality.

Optical Illusions can use color, light or patterns to create images that can cheat our brains. Our eyes processed an information that in reality does not match the real image. They occur because or brain is trying to translate what we see to make sense in our real world. They tric our brain into seeing things  which may or may not be real.

M. C. Escher was a Dutch graphic artist and mathematic whose work include impossible objects, explorations of infinity, reflection, symmetry, perspective, polygons and tessellations. His work is well known and you probably recognize some of his paintings below:

We are now going to work on this idea creating an Optical Illusion. First we will draw different polygons in our paper, then we are going to draw paralel lines on it and after that we will color it in black and white filling the spaces in the picture with one color or the other as in the examples.

This are Victor Vasarely drawings. He was called the father of Opp Art. This style of modern painting also play with the sensations and the Optical Illusions.
