PVC tubing
Ensemble
"I love plastic of any kind; I like the shape of pipes, tubes... This plastic tube, I like it very much in the artistic sense, in the art-world sense. It’s very un-heroic, un-monumental. A plastic tube is not comical, it’s not strong enough to be comical, but it is never serious. Even the biggest piece of plastic PVC pipe won’t be serious. It will always be plastic tubing, it doesn’t lend itself to being phallic at the same time. You think it would become phallic, but it never does—or only in a silly way, and then it can be a little more humorous. So I like the passivity of it, the non-heroic side of it." [full text here]
