MOOD is a wearable accessory designed with music in mind. It combines visible sound with audible sound to enhance the listening experience. Six different lenses produce almost endless changes in optical effects. One of the moiré effects is the visual perception that occurs when observing a set of lines or points superimposed on another set of lines or points, where the set of lines differs in relative size, angle, or spacing.
