Love this. He did a show on the very complex and individualized structures built by Bowerbirds, too!

If I went onto an empty field (or, much harder, an overgrown field or forest, which is closer to what this little fish traversed) and tried to walk in a perfect circle, I couldn’t do it. Also, its structure was in three dimensions, so each depression and high part were also similar. And the pattern on the inside! The more I look at it, the more in awe I am of it.
