Could you open source the code? I think this tool would be really helpful for one of my professors in explaining gain margin for feedback systems.

Hi, yes, it's open source. My web site's github repo is at https://github.com/duetosymmetry/web-site/tree/customization . The JS for controlling the web toy is at https://github.com/duetosymmetry/web-site/blob/customization... . This relies on a modified version of Polynomial.js which I will hopefully get accepted upstream, but for now it's just on my fork at https://github.com/duetosymmetry/Polynomial.js/tree/Aberth (though this is also behind my local repo).
