Wave Lines

How this effect works

Each line is a flat horizontal path bent by two sine waves. For every x position, we add a big slow sine and a smaller faster one — two waves of different frequencies summed together stop looking mathematical and start looking organic, like water or terrain. Each line gets a slightly different phase offset, which is why neighbors flow together but never identically.

The waves also pass through an envelope — a curve that's zero at the edges and full in the middle — so every line stays pinned at both ends and swells in the center, like a plucked string. The accent layer simply paints every 4th line in the brand color at higher opacity: an almost embarrassingly cheap trick that instantly adds rhythm and depth to the whole field.
