Playing around with the simple transformation
           Y <- K*Y^2 -1
mentioned in Hugh Kenner's book review in a recent Byte produced a nice
progression (as advertised) from very regular oscillations to unpredictable
but quasi-periodic wave forms, as K goes from 1.1 to 1.72.  I'd love to
hear what these forms sound like. Are there any references to using
transformations (digital filters?) like these to produce "chaotic"
sounds ? Has anyone used an "instrument" of this sort in a recorded piece?
