消えゆく作品：朽ちる素材で作られたインスタレーション

Design an ephemeral public artwork made from materials guaranteed to decay, photographed partway through its disappearance. Show a large form some six metres tall built entirely from natural gathered material — bundled dry reeds, stacked fallen branches, woven willow — assembled into a precise geometric shape whose sharp original geometry is now visibly softening. Detail the current state as roughly halfway through its life: one side still crisp and clearly built, the other sagged and slumped where rain has swollen and rotted the binding, with a section collapsed onto the ground and green shoots already growing up through the fallen material. Show the colour transition across the piece from the pale silvery tan of the still-dry material to the dark grey-brown of the sodden decaying part, with orange fungal growth appearing at the wet base. Detail the original craftsmanship as still legible in the intact portion — regular careful bundling, tight even lashings — making the loss more pointed. Show fallen debris scattered in a ring around the base and birds nesting in a hollow. Detail the surrounding meadow as reclaiming the footprint. Set it in a woodland clearing. Show soft damp overcast light. Photorealistic, decaying, tan to grey-brown with green, low three-quarter view.
