Vids. Perception puzzles, Visual Perception, Optical illusions and Paradoxes. This page illustrates that our visual perception cannot always be trusted.

Most optical illusions are the result of 1) incongruent design elements at opposite ends of parallel lines, 2) influence of background patterns on the overall design, 3) adjustment of our perception at the boundaries of areas of high contrast, 4) afterimages resulting from eye movements or from kinetic displays, or 5) inability to interpret the spatial structure of an object from the context provided by the picture.
