Tall vertical white barcode-like rectangles scattered across a black background. The bars form columnar stacks of varying heights, some very long near the left side and center, with a few shorter clusters toward the top-right. Each stack resembles a vertical sequence of evenly spaced horizontal lines. There is no readable text legible in the image, only repeating bar patterns. The overall composition gives a dam-like or skyline appearance with stark contrast between white bars and dark background.
