SpinRods

This program produces mathematical designs that are easily described using two-dimensional numbers which are commonly called “complex numbers.” While in SpinRods, you can press any of the function keys from F2 through F12 for demonstrations of various designs. For a brief introduction to SpinRods, press F1. For a more detailed introduction to the mathematics behind the designs, study the first 6 lessons in Powers of the Square Root of -1.
