The Logarithmic Scarf swirls with playful beauty and drapes in hard elegant lines, allowing one to interact (or in my case fidget) with this intuitive form.
You see logarithmic spirals every day. They are the natural growth curves of plants and seashells, the celebrated golden curve of ancient Greek mathematics and architecture, the optimal curve for highway turns, the soaring spiraled approach of a hawk to its prey, the great arms of tropical hurricanes and the nerves of the human cornea are all truly spira mirabilis.
