We describe a tiling approach to animating line-based Op Art. The tiling must be seamless along the tile edges, and we seek to minimize the number of bidirectional tiles because they interfere with the Op Art illusion. We introduce several algorithms for creating these tilings, and demonstrate that an optimal tiling can be found in polynomial time. Examples of animated Op Art can be found on our website https://sites.google.com/site/tiffanycinglis/research/animating-line-based-op-art.
