In the pre-XGA graphics days, you couldn't render a very good-looking Mandelbrot set on a computer screen, so I used to write programs that rendered on laser printers. The cluster of word processing PCs in the basement of my school's English building would chug away through the night, iterating polynomials.

Hello, David. I have been playing with your mandelbrot grapher all this week. It is incredibly simple, elegant, effective. And it is beginning to affect the way I think. Thank you for chugging away, and thanks for iterating those polynomials. MANY THANKS.
Now all you need is an iPad app. ;)
Anyway, I haven't studied your convergence algorithm yet, or how it iterates from one picture to the next, but thought it a very strange effect.
I don't know how to modify your code, but I feel sure you would like the following suggestion as more computing power becomes available (3.3 GHz 4 core processors.) The current (Java?) applet doesn't make use of threading, and it could surprise people with performance if you supplemented the algorithm with code to make use of threading - it's a highly parallel process. Love the app.
Simple, genius code.
hi - I mentioned you on http://makeyourownmandelbrot.blogspot.co.uk/2014/08/pure-web-mandelbrot-explorers.html
