# 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.
