Cyberpunk oceanic display, melancholic mermaid centerpiece with crystalline cybernetics, entwined in a digital whirlpool. Bioluminescent tears merge with sorrowful neon sea creatures in a tragic dance, encapsulated within a holographic maelstrom of lost maritime souls. Vortex-like ambiance with reflective techno-elements and ghostly nautical echoes, resonating a deep-sea lament.
