Check out the Cloaca machines. An amazing setup of metal and plastic to mimic what evolution gave us millions of years ago. Part art, part engineering, this kind of device has a beauty of its own. From there, as pointed out by Jonah at The Frontal Cortex we see scientists taking the idea one step further for application research. Sounds like it will contribute to all sorts of medicinal research down the pipe, pun intended.
I'd love to fill it with a bunch of cheeseburgers and see if it gets all queasy.
