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/

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

You also may want to look at https://linas.org/art-gallery/escape/smooth.html

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

No luck on android 5.1.0 with Chrome 47.0.2526.83 for me, just a black screen. No errors in the console either. Sorry I can't give you a more helpful description.

edit: that's for the submitted link, http://jonathan-potter.github.io/Mandelbrot/ works fine.
