  This project was built using code I wrote previously for this pure javascript fractal renderer: http://jonathan-potter.github.io/Mandelbrot/

  Jamie Wong's post on hacker news earlier this week was a massive help in allowing me to switch to using WebGL for the rendering portion. His post can be found here: http://jamie-wong.com/2016/07/06/metaballs-and-webgl/

  If you zoom in, then the oscillations get amplified and it because rather difficult to see anything.

  There are a lot of noisy visual artifacts over time. Seems like just one sample per pixel?

  Complex numbers offer an orthogonal dimension to the integer number line , where multiplication aquires a rotational element. This allows intermediate 90° (π/2) multiplication and Julia's Set is shown to be a map to Madelbrot's Fractal. https://acko.net/blog/how-to-fold-a-julia-fractal/

  Also the fourier transform is much more obvious in the imaginary plane. https://acko.net/tv/toolsforthought/

  I like fractal renderers, I made one in Haskell[1] once. In only 41 lines of code (23 if you strip white lines and type sigs). It also makes a post of its output combined with the code[3]; warning 18MB PDF (sorry Github).

  You should add a stop button for the animation, and also fix the back button. Using URL fragments for this is ridiculous.
