Here's another one! I loved the seemingly perfect symmetry of it. It was kind of a beast to draw and it took 2 or 3 tries to get all of the "leaves" to be the perfect widths. The top is a perfect circle, but there's an interesting skew on it that makes it look like an imperfect squished circle.
I have serious respect for whoever originally designed it. Recreating these things is really fun, and it's showing me how unintuitive these shapes are. They seem easy and obvious when you look at them, but then in recreating them you realize that some really unconventional and skillful thought had to be applied to achieve balance.
