Movement in artwork refers to guiding the eye across the composition through lines, shapes, or colors. It creates unity. Rhythm is the regular repetition of elements that forms a pattern. Both movement and rhythm can be created through repetition of lines, shapes, colors, or styles. Movement implies a sense of flow or direction, while rhythm provides overall structure through consistent repetition. Van Gogh's Starry Night uses the unique painting of clouds to create movement from left to right and repetitive star shapes to build rhythm.
