I have made a couple of little ones from a recipe I found on Ravelry. I'm a newbie so I can't give you a clickable link, but if you search Ravelry for "Hyperbolic Pseudosphere Scrubbie" you will find it, as you will if you google the same phrase. Very simple and satisfying!
More information will come to light if you Google "non euclidean crochet"
Enjoy!
