Flowers shaders v5 — Orbit pearls
The pearls move outside the tornado and corkscrew around it, printing a travelling spiral wave onto the braid.
In v4 the pearls fell inside the funnel and their influence was purely axial. Here they fall on the outside, each orbiting at its own radius beyond the pipes, with an optional swirl that makes them corkscrew around the structure on the way down.
The swirl is a whole number of turns per fall, so the wrap back to the top stays seamless. Several staggered pearls chasing each other down a helical path combine into a spiral wave that travels along the braid — the deformation becomes a pattern rather than a set of dents.
