Visualize a futuristic cityscape at night, with towering skyscrapers and neon lights, but instead of humans, the streets are filled with robotic twins, symbolizing the Gemini's connection to technology and innovation, with a hint of a binary code in the background.

Design an image of a Gemini zodiac sign, with the twins Castor and Pollux at its center, surrounded by a halo of light, with a subtle gradient of blue and white hues to evoke a sense of celestial wonder and magic.

Create an illustration of a pair of twins, representing the celestial twins Gemini, standing back-to-back, looking out at the vast starry night sky, with a subtle glow emanating from their bodies, symbolizing their connection to the stars and their role as the guardians of the zodiac.
