Churros v9 — Pasta scanner
Blue and red crosshairs pin the two ends of a kneading colour arch while a pale circle scans stamp by stamp along everything between them.
The strand arches over the lower frame in red, teal and cyan, a full-frame blue crosshair riding its start point, a red one riding its end, and a lavender circle travelling the body between them. Both anchor points wander, so the crosshair pairs slide across the canvas as the dough works, always cross-referencing the same two hidden spots.
Unlike its fixer siblings, the scanner changes nothing: the whole strand twists at one uniform doubled rate, and the sweep index only decides which stamp wears the circle this frame. The start and end markers are drawn at the first and last step of the walk before rotation is applied, which is why they stay axis-aligned while the ribbon corkscrews around them.
