3D render of a sci-fi baroque concept design featuring an anatomically correct brain device encased in a delicate terrarium, blending steampunk aesthetics with intricate scientific details. The brain is interwoven with ornate metallic gears and copper tubes, pulsating with ethereal blue and green luminescence, reflecting a fusion of organic and mechanical elements. Delicate glass panels form the terrarium, with condensation subtly collecting on its surface, while tiny ecosystems of moss and miniature ferns thrive within. The overall appearance is hyper-detailed and photorealistic, embodying a visionary blend of nature and advanced technology.
