Ledger Cylinder

Component

About

A scroll-driven stats section that paints large stat numbers and labels onto the inside wall of a WebGL cylinder, rotating the ring as the user scrolls, with a static accessible fallback for reduced motion.

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Ledger Cylinder to your project and fits it to your theme.

Code

How Ledger Cylinder is used: the demo's code. The component's own source comes with a free account.
