プロジェクションマッピング：既存ファサードへの一時的な作品

Design a temporary projection artwork mapped precisely onto an existing historic building facade. Show a nineteenth-century stone frontage with pilasters, cornices, arched windows and a pediment, at night, with a projected image aligned exactly to its geometry so the light appears to belong to the architecture rather than to be cast on it. Detail the mapping as exploiting the real relief: the projection making individual stone blocks appear to slide out of the wall and hang in space, the cornice appearing to peel away, the window arches filled with an image that respects their curve precisely. Show the projection's colour as restrained — mostly a cool white and pale blue that reads as light rather than as picture, with a single warm accent picking out the pediment — so the building's own materiality stays visible beneath. Detail the physical evidence of the projection honestly: a faint beam visible in the night air, a slight softness at the edges of the mapped area, and the un-projected parts of the building falling into genuine darkness. Show a crowd in the square below, their faces lit by the reflected light, phones raised. Detail the wet paving returning a broken reflection. Set it in a European-style civic square at night. Photorealistic, luminous, cool white on stone, low upward view.
