I have often used moiré effects in the designs of my kinetic sculptures. You will notice them especially in my sculptures with stronger optical designs like Shimmer , Radiance or Illusion. A moiré effect is a “secondary and visually evident superimposed pattern created when two patterns overlap” but they aren't limited to forms in motion. Andrea Minini is a graphic designer based in Milan that uses this effect in a very different application. She creates vibrant posters of abstract animals using the moiré effect. Here are some dramatic examples.
