Didn't someone mention the idea of a digital simulation using arithmetic methods to
produce a sound file?  

Was that done?

I would think that since while not animated, it is periodic (i.e., the pattern
repeats ever cycle), it shouldn't sound like s**t.  Wouldn't periodicity give rise
to a standard set of harmonics?

Why would it sound like s**t?  

Even while animating the "PWM", I can't see why it would sound any worse than a PWM
pulse wave.
