What kind of calligraphy is this? (NOT font ID)

The attached image is the work of designer David Rudnick, however I recently stumbled across a font in development on either this site or a different typography forum using this style as well, but I can't find it anywhere. If you know what I'm talking about a link would be cool, but since I have no other details, that's not the point of this post.

What style of lettering is this? The super-elongated, overly ornamented letterforms that intertwine with each other are so beautiful. I would love to learn more about it but have no information - anything would be appreciated.

Thanks!
