1969年，Keith Sonnier开始构思一组后来命名为“Ba-O-Ba”的系列作品。其中每一件都由大型玻璃面板及艺术家标志性的环形或方形霓虹灯管构成，将展览空间的墙面和地面贯通成为一体。

艺术家借用光和色彩“在空间中作画”，雕塑的传统限制由此被打破。“Ba-O-Ba”的构成比例来自于希腊数学中的“黄金分割”原理，通过Keith Sonnier非凡的艺术手段将建筑与光融汇为一体。

In 1969, Keith Sonnier began conceptualizing a series of works later named "Ba-O-Ba". Each of these pieces consists of large glass panels and the artist's signature ring or square neon tubes that connect the walls and floors of the exhibition space.

The artist uses light and color to "paint in space," breaking the traditional limits of sculpture. The "Ba-O-Ba" is based on the "Golden Section" principle of Greek mathematics, which combines architecture and light through Keith Sonnier's extraordinary artistic approach.
