The paper is attributed to "Anonymous Authors" and the GitHub has an image saying "comming soon" [sic] added five days ago. Of course the image is generated using this technique, but it's anyone's guess what it represents, a person sitting for meditation?

This is pretty cool, but also spooky. For example it seems like this has good commercial promise, as well as a serious amount of work invested, very strange that there's no person or company taking credit yet.

(edited to add, I see now that "comming soon" uses the "o" from their "Ashtanga Yoga" example)
