   Hi mathgroupers!
   Does anybody know how to make a 2-dimensional plot of the equation

    (1+z^2)^2 + 2*z*(1-z)*r = 0 ?

  where z is a complex variable and r is a real variable in the interval

    I would like to plot the solutions of the zeroes in the z variable
in the complex plane. I konw it is a closed curve and I'd like to get
its picture.

  Thanks in advance.
