// Description: symmetry experiment with ellipse for patterns
//-------------------------------------------------------------


//**INPUT**
size(400,400);
background (0);
smooth();
noFill();
strokeWeight(1);

//**DECLARATION & INITIALIZATION**
int spacer = width/50 + height/50; // modifier relative to canvas size

//**OUTPUT**
for (int b = 0; b < spacer*2 ; b++) {
  ellipseMode(CORNER);
  stroke (color(255,map(b,0,spacer*2-1,0,255),0));
  ellipse (width/2-spacer, height/2+spacer, b*spacer,  -b*spacer);//top right
  ellipse (width/2+spacer, height/2+spacer, -b*spacer,  -b*spacer);//top left
  ellipse (width/2-spacer, height/2-spacer, b*spacer,  b*spacer); //bottom right
  ellipse (width/2+spacer, height/2-spacer, -b*spacer,  b*spacer);//bottom left
}
