This document presents a collection of optical illusions intended to trick the eye and mind. It includes images that appear to change between two figures depending on perspective, such as a young or old woman. It also includes visual puzzles that challenge the viewer's perception of size, distance, movement and counting of objects. The overall message is that vision can deceive and it's important not to always believe what you see visually.
