euler sphere

Mathematical marvels known as Euler spirals are strategically positioned at every edge of an intricate geometric shape called a rhombic tricontahedron. These spirals are then inflated, radiating outward onto the surface of a perfectly spherical object. For those interested in delving deeper into the OpenSCAD code that brings this concept to life, a visit to http://www.whitehydra.com/euler_sphere.html is highly recommended.
