Rhythm (visual) - Rhythm is the sense of movment that is established through repetition of shapes. Visual rhythm is similar to musical rhythm -- music can be created through a pattern of sound and silence; visual rhythm can be created through a pattern of figure and ground. Rhythm, in contrast to repetition, does not require exactness; rhythm may have regular or periodic changes in size, color, texture, shape, etc. Visual rhythm will generally follow a path of arranged shapes. The path may be regular or irregular depending on the type of rhythm,
