Riley is one of the foremost Op Art practitioners whose geometric compositions create powerful optical illusions of movement and depth on flat surfaces, directly paralleling Vasarely's approach in Calcis. Her precise manipulation of shape and color to generate kinetic visual energy mirrors the dynamic abstraction seen in this specific work.

Anuszkiewicz was a central figure in the Op Art movement who created vibrant geometric abstractions using color relationships and repeated forms to produce optical pulsation and illusory depth, qualities that directly echo the visual language of Calcis. His works share Vasarely's commitment to colorful, mathematically structured compositions that trick the eye into perceiving movement.

Cruz-Diez dedicated his practice to exploring how color and geometric structure interact to create perceptual instability and kinetic sensation, making his work a close conceptual parallel to Calcis. Like Vasarely, he used systematic arrangements of color and form to generate optical movement that transforms a static surface into a visually dynamic experience.
