Create a stunning, high-resolution wallpaper featuring the Linux mascot, Tux the penguin, standing proudly in front of a sleek, futuristic cityscape. The background should include towering skyscrapers with glowing neon lights, a starry night sky, and a subtle circuit board pattern integrated into the design. The color palette should consist of shades of blue, black, and white, with a touch of green to represent the open-source nature of Linux. Tux should be detailed and charismatic, with a confident expression and a modern, tech-savvy appearance. --ar 16:9
