Korean woman in binary glass shutter gown on black marble

The Nanosecond Shutter Gown[ENVIRONMENT]High-gloss Nero Marquina marble floor, deep-black mirror reflections ($n=1.8$). Single 75-degree high-key spotlight. Matte black void background.[SUBJECT]Tall Korean woman, 20s, lithe hourglass, squared to camera. Porcelain skin, eye contact. Sleek, sharp Bordeaux red Mod bob. No sashes.[COUTURE & SCIENCE]She wears a "Kerr-Effect" gown composed of a matrix of liquid-filled glass cells. The garment acts as a high-speed Electro-Optic Shutter.[PHYSICS DIRECTIVE]Render a Binary State Material. Each cell on the gown must be either 100% transparent (showing her skin and the Bordeaux hair behind the collar) or 100% opaque obsidian black.[LIGHTING LOGIC]There are no gradients or "tinting." The opaque cells must be non-reflective, deep-void black, while the transparent cells must show perfect, undistorted clarity. The pattern should be a sharp, checkered "Digital Pulse" across her silhouette. The black marble floor must reflect the flickering binary pattern as a sharp, high-contrast mosaic of light and shadow.
