Abstract dark, metallic cubes scattered on a black background with glowing golden particles, in a minimalist and futuristic style.

Create a dark deep background for a mobile app interface. The background should fade from very dark charcoal at the top into a slightly lighter shade near the bottom. At the lower half, add abstract cubes shaped like Tetris blocks or bricks, arranged subtly and fading upward so they disappear by the mid-screen. Give these blocks a brushed silver or chrome accent finish so they look metallic but subdued. Add a faint carbon-fibre gloss texture across the entire background for a premium feel. Populate the scene with a light scattering of tiny dust particles or specks, softly glowing, as if suspended in air. Style should feel sleek, minimal, futuristic, and high-end — not cluttered. Resolution 1080×1920, transparent where possible. See more
