A 3D render of a sci-fi baroque concept design featuring an anatomically correct brain device intertwined with a lush terrarium. The device merges steampunk aesthetics with intricate gears and cogs, enveloping the brain in a transparent, dome-like structure. Within, a miniature ecosystem thrives, complete with delicate ferns and tiny blooming flowers. The hyper-detailed craftsmanship showcases a network of glowing filaments and copper tubes, linking the brain's lobes to delicate glass chambers filled with swirling, luminescent liquids. The entire piece is grounded on a polished brass base, with ornate etchings and mechanisms subtly whirring, combining scientific precision with baroque elegance in a photorealistic portrayal.
