This has been rendered using the open source "Processing". I came across it just last night and found it really helpful.
This below is the source code for it:

float r,x1,x2,y1,y2,x3,y3,a=0.55,b=0.65;
int i;
float theta,theta1;
void setup(){
size(350,350);
smooth();
r=340.0f;
}
void draw() {
background(255);
translate(width,height);
for(i=0;i<72;i++) {
theta=i*2*3.14/72;
theta1=(i+1)*6.28/72;
x2=r*sin(theta);
y2=r*cos(theta);
x3=r*sin(theta1);
y3=r*cos(theta1);
x1=x2*0.2;
y1=y2*0.2;
stroke(#ffff00);
line(x1,y1,x2,y2);
stroke(0);
line(x1,y1,0.2*x3,0.2*y3);
line(x2,y2,x3,y3);
if(i%4==1) {
stroke(#00ff00);
line(a*x2,a*y2,b*x3,b*y3);
line(x1,y1,a*x2,a*y2);
}
if(i%4==2) {
stroke(#00ff00);
line(b*x2,b*y2,b*x3,b*y3);
line(b*x2,b*y2,x2,y2);
}
if(i%4==3) {
stroke(#00ff00);
line(b*x2,b*y2,a*x3,a*y3);
line(b*x2,b*y2,x2,y2);
}
if(i%4==0) {
stroke(#00ff00);
line(a*x2,a*y2,a*x3,a*y3);
line(x1,y1,a*x2,a*y2);
}
}
}
