Moiré Patterns
The term moiré originates from the french and describes a specific fabric, traditionally made of silk. It is created by pressing two layers of thin fabric onto each other when wet. The arrangement of the fibres in the two layers are almost identical but naturally contain small irregularities.
It is this imperfect similarity of the two fabrics which cause characteristic Moiré patterns which remain after the fabric has dried. This effect occurs with any two layers of patterns which are similar but not identical, be it though slight displacement or rotation. Caused by interference, if one layer is moved over the other, the moiré pattern changes and areas seem to morph continuously from light to dark and back again. Our interpretation invites to either move two hanging layers over each other manually, or just stand and stare at two automated patterns which move across each other like clockwork.
