🤓 Moving Moiré patterns are mesmerizing optical illusions created when two repeating patterns (like parallel lines or dots) are overlaid and one is shifted, rotated, or slid over the other

🎇 This interference produces entirely new, larger-scale geometric waves or moving shapes that trick the brain into seeing fluid motion

📚 When two slightly misaligned grids overlap, some open areas perfectly align (creating light regions), while others block each other (creating dark bands)

🔎 Moving the top layer slightly causes these dark bands to transform and sweep across the page at a magnified speed, creating a hypnotic wave or gear-like effect

🎞 This video shows examples of this plus how camera sensors create Moiré patterns when imaging things with fine patterns
