Like a spinning top's trail or a shell, a line winds around a center and continues outward. Rotation gives it more movement than a still radial motif.
Move the spiral's origin with `center`; increase `scale` for more bands. `strokeWidth` changes the line thickness, and `strokeFalloff` controls how much it thins farther from the center. `speed` sets rotation speed; negative values reverse its direction.
`speed` defaults to 1, so the pattern starts in motion. This generator needs no input layer. Fast rotation holds attention, so keep it away from text; lower `speed` or set it to 0 for a calmer background.
When to use
Use it for a background that draws the eye toward a center, an abstract transition, or a short intro that needs rotation. Avoid fast motion where it could make reading uncomfortable or distract from the task.
