Steampunk Eichel mit mechanischen Zahnrädern

Macro close-up of an ancient acorn split open, revealing intricate brass and copper gears sprouting from within like organic clockwork. Weathered metal cogs intertwine with delicate oak fibers, rust bleeding into natural wood grain. Dusty workshop lighting filters through particle-laden air, casting dramatic shadows across the mechanical-botanical hybrid. Steam wisps curl around oxidized gear teeth. Aged brass surfaces contrast with earthy brown textures. Industrial patina meets forest floor aesthetics. Detailed metalwork shows rivets, springs, and clockwork precision emerging from nature's seed. Atmospheric depth with selective focus on gear mechanisms.
