Geometric neon vector icon set

This is a digital grid of 16 graphic icons set against a deep black background. Each icon is composed of a clean, minimalist blue-outlined square or shape with vibrant cyan accents. The icons represent various abstract processes or states, such as movement, expansion, rotation, layering, and data flow. The style is distinctly tech-oriented, utilizing high-contrast, glowing neon-like colors. The layout is perfectly symmetrical, arranged in a 4x4 grid. The artistic technique appears to be vector illustration, characterized by crisp, geometric lines and a modern, modular design aesthetic suitable for UI/UX interface design or software documentation symbols. There is no depth or shadow, emphasizing the flat, graphic nature of the design.
