Impossible Architecture: Escher Stairwell Loop

Mind-bending 3D architectural loop: Infinite Penrose stairwell with glowing glass balustrades, photographed like a high-end ArchViz walkthrough. Camera: 16mm shift lens, steady cam glide forward through impossible geometry, seamless 10-second loop with matching start/end frames. Lighting: Cool 6500K moonlight from above, warm 3000K LED strips under each tread, volumetric fog at 0.05 density catching light shafts. Style: Blender Cycles with geometry nodes for procedural stair generation, glass BSDF with dispersion, emission shaders on handrails pulsing to ambient soundtrack. Subject: Moss growing in mortar joints via particle system, water droplets condensing on glass, subtle camera shake for handheld realism. 4K, 16:9, perfect for YouTube ambient loops and Patreon background assets.
