A cyberpunk-style digital illustration of a sleek, glowing modular cube structure floating in a neon-lit void, with interconnected smaller cubes branching off from it like a constellation. The main cube has translucent panels revealing intricate circuit-like pathways inside, pulsing with electric blue and magenta energy. Thin holographic data streams flow between the cubes, creating an elegant web of connections. The scene is bathed in deep purple shadows contrasted with sharp cyan and hot pink accent lighting. In the background, abstract geometric shapes suggest a vast digital cityscape fading into darkness. The composition emphasizes the idea of a self-contained application module seamlessly connecting to a larger system infrastructure, with a feeling of speed, modern technology, and effortless deployment.
