About
Black hole shader background in WebGL: an engraved accretion disc in crimson and silver line work, light jets and etched contour nebulae drift with the pointer and flare when held. Five presets, grain and band controls. Use as a hero or section background. No dependencies.
Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Etched Accretion to your project and fits it to your theme.
