Love the visuals, is the source code open? A nitpick, I should be able to click on "microphone" instead of having to aim at the small checkbox, this is easy if you wrap it in an HTML label tag.

It is, look at the page source.

I can't get it to display anything. The console is ablaze with CORS errors. Firefox 58, Fedora 27.

Reminds me of the Scan Processor Studies by Woody Vasulka & Brian O'Reilly. https://vimeo.com/7517418

Really eerie stuff.

The repo was only the source for the line drawing code.

Very nice and realistic effect. As a low-level electronics hobbyist I was pleasantly surprised to find "entry level" 50 MHz digital oscilloscopes in the $150-$200 range these days. I picked up a Siglent to help me through Horowitz & Hill's The Art of Electronics labs and it's been pretty fun. I also have used it just to see what's going on on a cheap digital level I bought with USB output and some other things. Definitely a neat tool. It does sit on the desk more than I'd like these days though.

This needs some samples
