"Design a poster background for a mechanical engineering club

"Design a poster background for a mechanical engineering club. The image should feature a blend of technical and creative elements: intricate gears, blueprints, and mechanical components. Use a color scheme of deep blues and grays, with accents of metallic silver. Include subtle gradients and a sleek, modern look to convey innovation and precision. The background should be dynamic yet professional, providing a strong foundation for text and club information."
