Here are two images I made with processing using basic shapes.
size(600,600);
background(255);
fill(255,0,0,128);
triangle(300,300,300,450,400,570);
triangle(300,300,450,300,570,200);
triangle(300,300,300,150,200,30);
triangle(300,300,150,300,30,400);
ellipse(300,300,300,300);
stroke(255);
background(192, 64, 0);
ellipse(100,200,100,100);
fill(52, 95, 300);
ellipse(200,200,100,100);
fill(255);
ellipse(300,200,100,100);
ellipse(200,100,100,100);
ellipse(200,300,100,100);
Nothing fancy here, just basic shapes.
