A stylized isometric 3D building made of living plant material, called “Photosap.” It looks like a hybrid between a tree and a solar panel. Thick, twisting roots anchor it into the ground, while wide, leaf-like structures stretch upward and outward to catch light. The top is semi-translucent, glowing faintly with bioluminescent veins. The building pulses with soft green light, and strange mossy vents slowly breathe. Small glowing bulbs or tendrils move gently, sensing the environment. The structure is organic, asymmetrical, and resembles something between a jungle organism and a power plant. Built for an alien city inhabited by insectoid or elfin creatures. Lots of texture: bark, sap, leaves, soft glowing elements, and moss. Fantasy, whimsical, slightly surreal.
