This is kind of interesting in a totally disturbing and disgusting way.
There's a sculpture at the Universite du Quebec's art gallery in Montreal (show running through Valentine's Day) called Cloaca No. 5 that reproduces the human digestive tract - burps, farts, poo and all.
The machine is fed, it digests, and then at the end of the day it does it's business, all in the name of art.
Despite reproducing a bodily function, the creator doesn't believe his contraption belongs in a science museum.
"I don't have that ego," he said, with a chuckle. "I'm not helping sick people. I'm practically useless in society."
