Moiré Pattern Illusion
The interference of two worlds. Emergent geometry in action.
🧐 What do you see?▼
Two grids of identical parallel lines are overlaid. As the top grid rotates, giant "waves" or "shimmers" appear that are much larger than the original strips. These are the Moiré Bands.
🧠 Why this works▼
Moiré patterns occur when two similar periodic patterns are overlaid with a slight difference in angle or pitch. Where the lines of the two patterns align, light passes through (creating light bands). Where they misalign, the space is blocked (creating dark bands).
The resulting pattern acts as a Visual Amplifier, makes tiny misalignments visible to the naked eye. This is used in engineering to detect microscopic stress in metal.
🧪 Try variations▼
Adjust Intensity to change the width of the lines. Thicker lines create more dramatic, heavy interference, while thin lines create "shimmering" high-frequency patterns.
