Aurora Canvas

Prompt

Aurora Canvas
generative-art toy using canvas or WebGL (no libraries). Thousands of glowing particles flow through a Perlin/simplex-noise field and are attracted to the pointer or touch, leaving aurora-like light trails. Add 6 palettes (Aurora, Sunset, Ocean, Neon, Ember, Monochrome), a symmetry mode (4/6/8-fold kaleidoscope), and a toggle that lets the microphone amplitude drive the flow and brightness (with permission and graceful fallback). Add a clean hidden-on-idle control panel, a “Capture” button that saves a PNG, and a “Zen mode” that auto-animates. Smooth 60fps, mobile-friendly, mesmerizing.
