نصب مثلث بنروز الخرساني المستحيل

An aerial photograph of the Penrose impossible triangle built as a massive real [concrete] monument. An [architect] stands on one beam, casting a physically plausible directional shadow across the rough surface. Hard daylight casting sharp architectural shadows, highly detailed architectural photography style, optical illusion perspective captured from a precise elevated angle, extreme photorealism with realistic weathering and ground textures.
