A photorealistic 3D render of a sci-fi baroque concept design featuring an anatomically precise brain device intricately combined with a terrarium. This creation boasts steampunk aesthetics with complex, detailed, and scientific elements. The brain device, encased within a delicate glass dome, nurtures a miniature ecosystem filled with verdant plants and bioluminescent organisms. Copper and brass gears intermingle with vines and roots, creating a harmonious blend of nature and machinery. Tiny steam vents and clockwork mechanisms subtly animate the scene, alluding to a hidden intelligence. The composition, bathed in warm, diffused light, enhances the hyper-detailed craftsmanship and the organic-mechanical symbiosis.
