悬浮的物件：离地三米的不落地作品

Design a public artwork that deliberately never touches the ground. Show a large form — a rounded mass some six metres across, part boulder and part cloud in character — hanging in mid-air three metres above a plaza, suspended on four almost invisible stainless steel cables running up to anchor points on the surrounding building facades. Detail the cables as very fine, no more than eight millimetres, and unlit, so at a distance they vanish entirely and the mass appears to hover unsupported. Show the underside of the form as the most carefully finished surface, since it is the one everybody sees: smoothly modelled, pale, and slightly concave so it gathers reflected light from the paving and glows faintly. Detail the mass as fabricated in glass-fibre composite over a light aluminium frame, its outer surface a matte off-white with a subtle mottled texture, so it reads as heavy while being light enough to hang. Show the empty ground beneath as clean unobstructed paving that people walk straight through, several pausing to look up. Detail the shadow it casts as a soft dark ellipse directly below. Set it in a plaza enclosed by mid-rise buildings. Show bright overcast light. Photorealistic, floating, pale mass against grey sky, low upward view.
