Great stuff! I did a little web searching and found this page:
http://www.falstad.com/fourier/You can choose pre-defined waveforms or draw your own, either by
drawing the waveform or changing the levels of the harmonics. And
then you can hear the sound! As you'd expect (assuming you're into
fourier series and the math of music), the pulse on the sawtooth
increases the harmonics (brighter tone).
