Moiré pattern

An example of the moiré pattern

A moiré pattern is a type of pattern that appears when two similar patterns are overlaid on top of each other. The overlapping creates a new pattern that can be different from the original patterns. This new pattern is usually wavy and can be seen in various materials, such as textiles or photographs.
