A Wolfram Demonstration titled Combinations of Sines in the Complex Plane by Stephen Wolfram. He writes "Combinations of two sine functions must always have their zeros on the real line. Combinations of three need not. The height here is the absolute value of the sum of sine functions; the hue is the phase."

These images are from a Wolfram Demonstration by Michael Schreiber titled Complex Exponential Resonance. He writes "Complex exponentials of complex exponentials feature resonance patterns. There is only one polygon; black regions are under an odd number of self-overlays."

This sculpture is 8 feet in diameter and, from what I can tell, is a compound of five octahedra (a stellation of the icosahedron). The designs are projected onto its surface.
