Paul,
  Re: Your "...somebody else might like playing with [the equation]."
 
I rendered the "Farting Monkey equation:"
 
> f[x,c]=c*x*(x^2 - 2*x + 1)/(x^3 - x^2 - 2*x + 1)
> Domain:{x,y}={{-2,3},{-2.5,2.5}}
 
as...
 
FartMonk { ; Roger Bagula via Paul N. Lee
z2=z*z
zt2=z*2
z3=z2*z
c=pixel
z=pixel:
a=c*z*(z2-zt2+1)
b=z3-z2-zt2+1
z=a/b
|z|<4 }
 
...and get a humdrum circle with a few minor non-circular areas. 
 
Have I missed something?   Anyone have any ideas?     <---<<
