There is also a phenomenon called chromatic aberration, caused by distortion of a camera lens, which appears like this: | |||

Also, as the size of an aperture like the iris increases, diffraction distortions become apparent: | |||

For example, moss on a rock could physically shift from green to red to blue to any other color and then back to green again in the visual style of a smooth and seamless animated loop. | ||
