空中纤维网：随风起伏的巨大软雕塑

Design an aerial sculpture in the manner of Janet Echelman, suspended high above a city plaza and made entirely of knotted netting. Show a vast volumetric net some sixty metres across, hung from cables anchored to the surrounding rooftops and to two slim masts, floating twenty or more metres above the ground with nothing beneath it, so the space below stays completely open. Detail the form as a series of nested undulating rings and hollows — a shape derived from a rippled surface rather than from any solid object — its depth varying so parts billow downward into soft pockets and others draw up tight. Detail the material as hand-spliced and machine-loomed high-tenacity polyester twine in graduated colours, deep magenta at the outer edge blending through orange to pale gold at the centre, the mesh open enough that sky and cloud read straight through it everywhere. Show the whole mass moving in the wind — one side lifting, the netting rippling in slow waves — so the sculpture is never the same shape twice. Set it above a paved urban square with towers around. Show late-afternoon sun passing through the mesh from behind. Photorealistic, weightless, magenta and gold against blue, upward view from directly beneath.
