Moiré patterns are an optical illusion, that illustrate visually what a cross-modulated sound would look like.
There is an interference between two visually layered textures, and our sight. This interference creates secondary wave-forms, or ripples that distort and overwhelm the true object or image.
This is similar to how more complex sound waves are generated when two or more single-cycle frequencies are modulated.
A moiré pattern is created when a coordinated series of (slightly differently coloured) concentric rings are repeatedly drawn and moved.
Apart from the moiré, many different patterns and colours emerge from this internal dialogue.
