It's a very straightforward concept. A small hexagon is collapsed to the next larger. The petal shapes radiate out from there. Since the shapes don't flow seamlessly into one another, there are some blunted pyramid shapes to connect them all.
In my imagination this looked much more beautiful than it turned out in real life. Perhaps I was too ambitious and there should've been greater negative space between the iterations.
I still love the concept. The mechanics of it are wonderful. I just wish it yielded a more pleasing visual result. What do you think?
