This application is a laboratory for the creation of automata. An automaton is a system of circles (actually planar coordinate systems) moving relative to one another in a hierarchical fashion. That is, every circle in the system except one will be rolling along the circumference of one other circle at every moment in time. Automata are a superset of the mathematical curves called epicycloids and hypocycloids.

This application demonstrates the curious relationships wherein a tetrahedron can be inscribed in a cube in two different ways and a cube can be inscribed in a dodecahedron in 5 different ways. It also demonstrates a kind of quantum fluctuation or beating as a heart does, in which the tetrahedron oscillates back and forth between the two positions in which it can be inscribed in the cube, and in which the cube oscillates within the dodecahedron.

One might wonder if there is a 3-dimensional golden-rectangular-solid that is analagous to the 2-dimensional golden-rectangle, which can be sub-divided recursively so that each left-over rectangular solid has the same proportions as the original rectangular solid. The 3D analogue to the 2D golden rectangle does indeed exist, and is depicted by this application.

Phyllotaxis is the study of the successive arrangement of radial parts of a growing plant, such as the leaves on a stem, or the seeds in the head of a sunflower. This application generates a simple phyllotaxic arrangement of circles, expanding outward at either a linear or an exponential rate. You can specify the angle between each circle (between 0 and 360 degrees), and you can determine rate of expansion using a pair of slider controls.
