--------------------------------------------------------

A single-color animated spiral that morphs across a huge range of looks — from crisp, thin-lined geometric spirals to flowing whirlpool shapes and wavy, abstract rings, all from one shader with deep stroke and distortion control.

Features

  • Perspective density — simulate spacing falloff toward the center for a flat or deeply "sucked in" spiral look

  • Distortion control — warp the spiral shape organically along its curve

  • Full stroke control — adjust Stroke Width, Taper (fading toward center), and Cap (extra thickness at the center)

  • Noise layer — add noise distortion with its own frequency control for a rougher, less mechanical curve

  • Softness control — go from a hard, high-contrast edge to a smooth, blended transition

  • Fully animated — smooth, continuous motion by default, with full control over speed

  • Built in Paper style, running on a lightweight, zero-dependency shader engine for smooth performance

How to use

  1. Add the Spiral component onto your canvas

  2. Set your Background and Foreground colors

  3. Adjust Density and Distortion to shape the overall spiral form — flat and geometric, or deep and whirlpool-like

  4. Fine-tune Stroke Width, Stroke Taper, and Stroke Cap to style the curve itself

  5. Add Noise and Noise Frequency for a rougher, hand-drawn feel

  6. Set Speed to control animation pace, or set it to 0 to freeze on a single frame
