Hi Guys :) This is an updated version of an animation program variation written in 2015, and updated in 2018, for Fourier Series Saw Wave Approximation. A new circle is introduced for every second rotation of the original circle. The colours of the waveforms are rotated so that the yellow wave is always the newest iteration, and for that reason, there is a peculiar quirk for every odd wav gradient.
