Kinetic Coin Ring Fifteen metallic coin-like discs rotate in a circular arrangement under warm reflected light. Radial Material Study · 2026 How it is made Cylinder geometries are positioned procedurally around one radial group. A timed intro expands their radius and scale, sine waves create the breathing motion, and GSAP transitions the physical materials between coral and monochrome themes inside an HDR-lit environment. Techniques: Procedural radial layout · MeshPhysicalMaterial · GSAP material tweening · HDR environment This interactive WebGL sketch requires JavaScript.
