       | Looks like it is using processing to do the animation.

         | I think that we need't use processing for animation. In fact,
         | Geogebra is easy to accomplish them.

       | Seeing an epicycles animation years ago did wonders for my
       | understanding of the complex representation of Fourier series,
       | and I've been looking for that animation ever since to share with
       | others getting into signals for the first time. This post far
       | surpasses that page though! Excellent work, excited to share it
       | with people in the future.

       | Very cool. Thank you for making and sharing this
       | 
       | How are the animations made? Are they gifs or svgs or canvas +
       | js, something else?

       | This is an excellent review with animations that make the math
       | visually intuitive. I love how it grows from the simple to the
       | ridiculously complex at a reasonable pace.

       | Thanks, great examples and wonderful website. It's crazy how this
       | site is handled with ease, yet most static news sites I visit
       | constantly crash my browser.

       | combine.
