# Sculpture Hero

> Split hero with a raymarched WebGL sculpture: a breathing torus with three orbs melting through it, shaded as iridescent lacquer with anti-aliased edges on a transparent canvas. It turns toward the cursor over a receding ring floor, with floating glass callouts. No three.js; one fragment shader.
