// Great example! Thanks
// I modified slightly to make a circle based fractal

void setup() {
size(400,400);
smooth();
}

void draw() {
background(255);
stroke(0);
branch(width/2, height/2, 400);
}

void branch(float x, float y, float dia) {
ellipse(x,y,dia,dia);
if(dia > 2) {
branch(x,y-dia/4, dia/2);
branch(x,y+dia/4, dia/2);
}
}

Phew it makes sense now! I had started down the wrong path of drawing

line(x,y, x *1.5, h);
line(x,y, x *0.5, h);

Thanks,

Excellent book by the way!

Finally, I have to understand the code by a stupid way (draw each points then connect them on paper), and I think it’s obviously not an advanced way of thinking, so, could you please show me a smarter way of thinking the code above? Thank you.
