        Schools should let kids play with two sinusoidal signals on an oscilloscope in x-y mode, varying their frequencies and phases. It really solidifies the concepts learned in maths.

        You should check out John Whitney, Sr. - the father of computer graphics. He started before they had digital computers, creative patterns like this using clockwork controlling a light drawing directly on film. Here is Arabesque:https://youtu.be/HnlQa74H7is

        Does harmonic motion just mean that they are created with trig functions? That word harmonic always confuses me.

        it means motion along a line where the force is proportional to the distance from some point on the line. "simple" in this context means you assume no friction etc so it goes on forever. eg a weight on a spring; with no friction, the weight will bounce up and down 1/
