I'm going to forget about that dsp.js now and just write my own algorithms; the sound and the image are close enough for perceptible synchrony:

I did say I'd next go back and look at more examples, but that would take up all of the day's creativePact time, so instead I'll implement a different synthesis method and maybe some interactivity on the canvas too.
