Attach their codes, too.

Code:

```
def f(z):
x = real(z)
y = imaginary(z)
return (x^2 + y^2 -1)^3 - x^2*y^3
complex_plot(lambda z: (1/f(z)*i^(z+1)),(-1.5,1.5),(-1.5,1.5),plot_points=300)
```

(The code takes a lot of time to run, for testing purposes run with plot_points=50)

I've lost the exact code for this but it is somewhat like this:

POV-Ray Code:

```
#declare e = 2.71828;
#include "textures.inc"
#include "colors.inc"
#include "glass.inc"
camera {
location <0, 0, -10>

}
light_source
{

color rgb <1.0, 1.0, 1.0>
shadowless
spotlight
rotate y*clock*-100
}
#declare Ball =
sphere{<0,0,0>,0.08
texture{
pigment{color rgb<1,0.8,0>}
finish {diffuse 0.9 phong 1}
}// end of texture
}// end of sphere
//------------------------------------
#declare X = -5; // start value X
#declare EndX = 5; // end value X
#declare Step = 0.001;// step value
#declare Sine =
union{
#while ( X < EndX + Step)//loop start
object{ Ball translate <X,sin(X),0>}
#declare X = X + Step; // next X
#end // ------------------- loop end
};
#declare X = -5; // start value X
#declare EndX = 5; // end value X
#declare Step = 0.001;// step value
#declare Curvedd =
union{
#while ( X < EndX + Step)//loop start
object{ Ball pigment {color rgb<0,0,1>} translate <X,cos(X)+cos(pow(X,2)),0>}
#declare X = X + Step; // next X
#end // ------------------- loop end
};
#declare X = 0; // start value X
#declare EndX = 6.28; // end value X
#declare Step = 0.001;// step value
#declare Cardioid =

#declare r = 1 - sin(X);

#declare X = X + Step; // next X
#end}; // ------------------- loop end
#declare X = 0; // start value X
#declare EndX = 6.28; // end value X
#declare Step = 0.001;// step value
#declare Butterfly =

#declare r = pow(e,sin(X)) - 2*cos(4*X) + pow(sin((2*X-pi)/24),5);

#declare X = X + Step; // next X
#end}; // ------------------- loop end
#declare X = -6.28; // start value X
#declare EndX = 6.28*2
; // end value X
#declare Step = 0.001;// step value
#declare log_spiral =

#while ( X < EndX + Step)//loop start
#declare b = log(1.61803397)/(3.14159/2);
#declare r = 1*pow(e,b*X);
object{ Ball texture{Gold_Metal} translate <r*cos(X),r*sin(X),0>}
#declare X = X + Step; // next X
#end}; // ------------------- loop end
#declare X = -6.28; // start value X
#declare EndX = 6.28
; // end value X
#declare Step = 0.001;// step value
#declare Fermat_spiral =
union{
#while ( X < EndX + Step)//loop start
#declare r = pow(X,0.5);
object{ Ball texture{Polished_Brass} translate <r*cos(X),r*sin(X),0>}
#declare r = -1*pow(X,0.5);
object{ Ball texture{Polished_Brass} translate <r*cos(X),r*sin(X),0>}
#declare X = X + Step; // next X
#end}; // ------------------- loop end
object {Butterfly texture{Jade}}
/*object {Cardioid}
object {Sine}
object {Curvedd}
object {Fermat_spiral}
object {log_spiral}*/
sphere{ <0,0,0>, 1
texture{T_Glass3
} // end of texture
interior
{I_Glass_Fade_Sqr1}
finish
{F_Glass1}
scale 100
}
```

Uncomment any of the lines in this portion of the code above as you wish:

```
object {Butterfly texture{Jade}}
/*object {Cardioid}
object {Sine}
object {Curvedd}
object {Fermat_spiral}
object {log_spiral}*/
```
