##      During one all-night randomly-generated sequence (see p-* files),
##      I was aware of a really strong effect from one set of tones, so I
##      awoke to take a note of the tone-set.  This was it.  For some reason
##      I can't remember, I called it 'purring cat'.  It doesn't have quite 
##      the effect now, so maybe I need to be deep already for it to work.
