Circle on a divided curve is useful when you want to create a circular pattern in a curvilinear manner for movement diagrams or laserprinting.

Check out how coral reefs can be modeled by crocheting

\”Beautiful Math of Coral\” a TED talk by Margaret Wertheim

Did anyone say we can’t be inspired by a structure under the ocean for a manmade form that extends high above the sea level?  In fact, conceptually and physically, coral reefs hold various characteristics that resemble what a skyscraper is generally defined as.

First of all, a coral reef is a community within a larger community; as a component of a larger ecosystem, it includes multiple biological communities.  Likewise, skyscraper stands in an area side by side with other towers and buildings, and within it contains many kinds of offices, functions, and residences.  Such biological communities in coral reefs are colonies consisting of many individuals called polyps.  Polyps secrete a hard calcium carbonate skeleton, which serves as both a uniform base for the colony and protection against predators.  Coral reefs that we see are made of these skeletons building up over years.  I compare polyps to modular spaces that are contained in an exterior shell with windows.

From the perspective of parametric design, the forming of coral reefs is also similar to a skyscraper for its method and mathematically driven nature.  Depending on the species of coral and environmental conditions, the growth of coral reefs in size and form varies over time.  In a parametric composition, once a variable in a formula is changed, the whole is affected in its form.  The intriguing curves in coral reefs can be modeled as hyperbolic geometry which has no limit but infinity, which gives a potential to a skyscraper design that is cohesively but dynamically continuous.
