Optical Illusions

We can't always trust what we see. We are used to how things are supposed to look. If pieces are missing, sometimes our brain fills them in. Our brain puts information together in a way that makes sense and allows us to see optical illusions in different ways. Optical illusions have been studied for thousands of years. The ancient Greeks even used the principles of optical illusion in their architecture.
