Dark black background filled with a dense grid of tiny dots and dashes arranged in horizontal rows across the entire screen. Glowing light blue and cyan horizontal bar segments of varying lengths pulse and animate across the grid from right to left, like streaming data or a waveform visualizer. The bars shift, grow, and fade in a rhythmic wave pattern brighter and longer in the center, dimmer and shorter toward the edges. Subtle dark blue ambient glow. Minimalist tech aesthetic, data visualization, sci-fi UI, deep black void, cool blue neon light, smooth looping animation, no text, no characters.
