如果表演藝術中心是劇場，劇場的舞台上演的是人間百態；那麼參觀回路就像觀眾區，而整個劇場就概念地等於是舞台。這感覺在球劇場那段參觀回路感覺更強烈。球劇場內，觀眾看著舞台上演的人間百態，而參觀迴路的漫遊者則黃雀般在觀眾席後方凝視著整個劇場。因此參觀回路不只是功能性的通道，它也給與這機能性建築概念的意義。

讓不同機能交錯或堆疊，一向是OMA的偏愛，庫哈斯稱這是壅塞的文化（Culture of Congestion）。壅塞對OMA而言，有多元、豐富的意思，的確在上例子都讓我們體驗到出人意料的新經驗。（全文請見《實構築季刊》16期）

If the Performing Arts Center is a theater and various scenes in life are performed on its stage, then Publicloooooop is the auditorium, and the entire theater is conceptually equal to the stage. The feeling grows stronger at Publicloooooop around the Globe Playhouse. In the venue, the audience watches various scenes in life performed on stage, while the flaneurs at Publicloooooop gaze at the whole theater from behind the auditorium like canaries. Therefore, Publicloooooop does not simply serve as a functional passage; it also gives meanings of concepts to this functional architecture.

It has always been OMA’s preference to intertwine or layer different functions. Koolhaas called it Culture of Congestion. Congestion, to OMA, bears meanings of diversity and abundance, and the above examples indeed allow us to get a taste of unexpected new experiences.
