Ribbons v14
Chord strokes replace the beads: each stamp spans a quarter-turn of its own vector, sweeping dark wings that multiply in half-fold steps.
Dark blades sweep around the hub of a ray tunnel, edged with red, teal, blue and yellow glow, their count drifting upward through half-steps while blurred ghosts trail each pass.
Where the sibling versions stamp both endpoints of each stroke in the same spot, here the two endpoints are the same polar vector a quarter-turn apart, so every stamp is a real chord and the arms read as swept blades rather than bead chains. The fold count ladders through whole and half values with a very slow blend, and the coarse blur buffer supplies the trailing ghosts.
