A couple of artists have teamed up with the Czech-German Future Fund to create a vacuum robot that can sort rocks. The result is much more mesmerizing than that description, I promise.

The robot is called Jller, named for the German river where the aforementioned rocks were collected. Jller uses computer vision to sort pebbles from "any river" by geologic age, distinguishing between them by identifying features like the surface texture, grain, and composition of each stone.

I think that's pretty awesome? Honestly, I am more fascinated with watching Jller work than I am with whether or not this robot is going to disrupt geology. I'm not saying that a Facebook Live of this machine doing its thing would completely ruin my workday, but I'm not not saying that, either.
