Abstract
An image is disclosed comprised of flakes in a carrier, such as an ink vehicle or a paint that can be aligned in a magnetic field. The flakes are aligned so as to produce one or more kinematic features such as a rolling bar that appears to move as the image is tilted. These images can provide security features on high-value documents, such as bank notes.
