The superposition of point or line grids gives so-called Moiré patterns, an effect similar to interference, which results from the superposition of waves. Often linearly arranged grids give graphically interesting periodic patterns, but the transfer into sounds is remarkable. The sound used is a jazz guitar.
Most art is created by combining order and disorder. The aesthetic effect is influenced strongly by this relationship. With the help of interferences, you have a good chance of producing a variety of patterns with considerable aesthetic appeal.
