Acconci Studio | Klein Bottle Playground: Surfaces That Blur Inside and Out

A play structure composed of a continuous curved surface, where the surface lifts from the ground, twists, passes through itself, and returns to the ground, making it impossible to clearly distinguish which side is inside and which is outside—the act of climbing is simultaneously entering and leaving. The curved surface has circular holes of varying sizes, through which one can crawl or look. The material is fiberglass or painted steel plate, with a smooth surface and a single white or bright color. The logic of the structure comes from mathematics rather than childishness, but children's bodies will find their own ways to play. The surroundings are simple paving or sand. Shot under strong daylight, with clear continuity of the curved surface and shadows of the openings. Avoid: the structure being divided into clear inside and outside, adding decorations to the surface, adding stairs and handrails, concretizing the shape.

一件由連續的曲面構成的遊戲構造,表面從地面翻起、扭轉、穿過自己再回到地面,因此無法明確指出哪一面是內、哪一面是外——攀爬的動作同時是進入與離開。曲面上開著大小不一的圓洞,可以鑽過也可以看穿。材料為玻璃纖維或塗裝的鋼板,表面平滑,顏色為單一的白或亮色。構造的邏輯來自數學而非童趣,但孩子的身體會自己找到玩法。周圍為單純的鋪面或砂。日間強光下拍攝,曲面的連續與洞口的陰影清楚。避免:構造分成明確的內外、表面加裝飾、加設樓梯與扶手、造型具象化。
