Optical Illusions: Motion Patterns

A static pattern that induces strong illusory motion in peripheral vision, composed of repeated [ELEMENT SHAPE (e.g., sawtooth wedges / sinusoidal bands / contrasting diamonds)] arranged in a [LAYOUT (e.g., circular radiating array / horizontal rows / concentric rings)] ::4 Morphology: Luminance‑defined edges arranged with a systematic phase shift between adjacent elements. High‑contrast high‑spatial‑frequency pattern. When the eyes move across it, the elements appear to flow or rotate smoothly. ::3 Material Physics: Exactly [2–3 COLORS (e.g., black, white, and a mid‑grey / blue, yellow, and white)] arranged in sharp, unblended steps. No texture, no gradients. ::3 Illumination: Flat; all colour bands have uniform luminance within themselves. ::2 Render Stack: Op‑art painting by Bridget Riley, Akiyoshi Kitaoka's motion illusions, neuroscience textbook figure on peripheral drift ::1 Negative: [actual animation, motion blur, gradients, asymmetric distortions, non‑repeating elements, soft edges] ::-1
