well, this code's a bit sloppy and ugly, but here it is.....

#declare major=+2.00;
#declare minor=+0.35;
#declare dis=+0.55;
#declare freq=9;

#declare a = function{cos(atan2(z,x)*freq)*dis}
#declare b = function{sin(atan2(z,x)*freq)*dis}
#declare c = function{(sqrt(x^2+z^2)-major-a)}
#declare d = function{sqrt((y-b)^2+c^2)-minor}

//one
#declare one=
isosurface
{
 function {d}
 contained_by{sphere {0,4.0}}
 eval
 method 2
 threshold 0

 pigment{color rgb 1}
 finish {blinn .9 facets .3 reflection .95}
 photons {target reflection on}
}

object{one}
