环形穹顶最初是为纽约艺术与建筑展览馆25周年纪念设计的用作店面的临时建筑。从那以后，它被安装到世界各地不同的地点，包括日本的北九州和横滨，以及意大利的米兰。这个穹顶形的结构直径为8.65m，由大约1 000个塑料呼啦圈组成。这些呼啦圈可以自由叠加，用大约1万个拉链绳固定连接在一起。这个结构的设计易于非专业的人员组装，比如学生、艺术家和其他志愿者。

这个项目的设计中实验、调整和近乎原始的装配方法，其主要目标不是最终的结果，而是通过人们参与建造的体验，营造更欢乐的气氛。只要简单地将拉链绳剪断，这些呼啦圈又可以重复使用或重新组合，而不用丢弃，这种更环保的方式让呼啦圈有可能恢复本来的用途。

呼啦圈由透明的白色PVC制成。到了夜晚，穹顶表面大约200个内置电光线的呼啦圈发出柔和的光亮，塑造出全新的环境。□（项琳斐 译）

The Ring Dome was original ly conceived as a temporary structure for the Storefront for Art and Architecture gal lery’s 25th anniversary in New York.Since then, it has been instal led at various locations around the world, including Kitakyushu and Yokohama,Japan, as wel l as Milan, Italy. It is a dome-shaped structure with a diameter of 8.65 meters, composed of about 1000 plastic hula hoops. The hula hoops are randomly layered and fastened together by about 10 000 zip ties. This structure was designed to be easily assembled by non-professionals such as students,artists and other volunteers.

Designed for experimentation, adjustments and an almost primitive assembly method, this project’s main objective was not the final result but more the celebratory, shared experience of constructing the piece. By simply severing the zip ties, the hula hoops could then be reused or redistributed, rather than discarded, making it possible to return the hula hoops to their original purpose in a more environmental ly friendly conclusion.

The hula hoops are made of translucent white PVC and at night, electroluminescent wires contained in about 200 hula hoops on the dome’s sur face glow gently and create a completely new environment.□
