Optical Illusions
Optical illusions are fun and sometimes difficult to understand. When you look at a picture, you may see something wrong, or you may not understand it correctly. There are many different optical illusions. Some are about shapes like squares, circles, triangles, rectangles or cubes; some are about lines, long lines or short lines; and some are only about pictures. For example, look at the picture here. What can you see? Do you see only one animal? You’re wrong! Look at the picture again. There are two animals on the picture. I won’t tell you what the animals are. You try to find them.
