Liquid Metal Skill

Produce a single self-contained index.html that renders a real-time metallic surface full-screen — molten chrome with an iridescent sheen — with a clean typographic overlay on top.

Why this is a powered artifact

OpenDesign detects getContext('webgl2') and renders this file in powered preview — a cross-origin-isolated iframe with allow-same-origin. The full GPU pipeline is available; you do not need to work around the opaque sandbox.

Workflow

Step 0 — Read the reference

Read example.html end to end. Note the shape: a domain-warped fbm height field; a surface normal reconstructed from that field's gradient (finite differences); metallic shading = diffuse chrome ramp + a sharp specular (pow(dot(n,h), 80)) + a fresnel term; and an iridescent cosine palette (0.5 + 0.5*cos(2π(x + phase))) driven by height and fresnel for the thin-film sheen.

Step 1 — Choose the surface

• Molten chrome (default): domain-warped fbm height, hard specular, cool grey base.
• **Holograp…
