Geometry is rarely motionless, generally extremely fast-moving,<ref name="2C-B"/> and self-changing in regards to its shape and style. During this process, the geometry naturally drifts laterally or radially across the visual field to create overlapping webs of geometric patterns which transition through many distinct states, all of which are visible within a single perceptual frame.
