Not a logo, but a "seal". The distinction makes sense, since the intricate design would not work well as logo I think. I found it beautiful, but obviously it's only "news" because of who created it.

As such, there is an argument that a seal refers to a physical object with physical imperfections, which are hard to reproduce. Note that the article is about the "design" for the seal, as distinct from the seal itself. Maybe the plan is to manufacture a physical seal off the design (complete with manufacturing imperfections) then use that to make impressions?
