A moving sculpture by Kaoru Matsumoto, using "titanium, stainless steel, bearings" and priced at $120,000.
"Moving, powered by wind. Moving, not as energy itself. Moving, gliding as a part.
Neither the cloud disrupted by the urban landscape nor the cloud that foretells the weather.
Rather the soft blanket, spreading across the vast skies, covering the meadows, like a cloud."
