Super Formula Guilloché Patterns in javascript/svg

I made this little graphical toy last month. I had intended to put a few finishing touches on it before blogging about it, but instead it has languished.

Enter a few numbers, press "update" and get a geometric pattern.

Requires a browser that supports svg, which must be most of them by now. I tested on Firefox and Chrome.

(Updated to actually link to the toy)
