The document discusses principles of visual organization in art such as shape, gestalt laws of grouping, figure and ground relationships, and achieving unity and variety. It specifically examines four gestalt laws - continuity, similarity, proximity, and closure - and how they influence human perception of patterns and objects. Additionally, it explores techniques artists use to create a sense of unity within a work such as repetition, continuation, color/value consistency, and use of line or a grid framework, while still incorporating sufficient variety for visual interest.
