An articulated array of polished metal arms and panels rotates individually in response to a simulated wind field, catching light like a living mechanism. Six levels of five arms each hold three hinged panels, whose target angle is driven by a layered sine/cosine pseudo-noise wind field function sampled at each panel's world position, then smoothly damped with a lerp for organic, lagged motion. A PMREM-generated environment map gives the metallic panels realistic reflections.
