This "wow" experience comes from the Magazine Publishers of America's Digital Awards.
Seed magazine put together a blog covering science and culture that's one of the most awesome feats of web design I've seen. Here's how Seed describes its Phylotaxis blog:
Related to the Fibonacci Sequence, Phylotaxis (Phyllos - leaf, Taxis - order) is the study of the ordered position of leaves on a plant stem, and also applies to the shape of pinecones, and the dispersion of seeds on the flat head of a sunflower. Seed has chosen this shape to represent the perfect synthesis of science and culture.
Works for me. I'm just mystified by it.
