This reminds me of the MASH episode where they had to make Korea look better to earn a prize.
They made an outdoor fountain out of bedpans.
The person from HQ who awarded the prize really liked the fountain.
So, if that was art, this qualifies just as well.
Of course, I also considered the plumbing exhibit I saw years ago at the Chicago Museum of Science and Industry that used clear pipes to also be a work of art.
There also used to be a web site that was showcasing the most interesting urinals that people would send in pictures of. Some of them were so artistic that if I did not know what they were, I would not have thought they had a function.
