I originally wanted to make broken eggs but that was very frustrating and I had no patience, but it inspired me to somehow think of ultrasounds and then I decided I wanted to make a colourful ultrasound to see what it would look like.
This is far from an ultrasound but maybe in an alternative universe its an abstract ultrasound. I tried various different codes and combinations/researched many different basic already existing codes and references till I finally got something that I wanted. Here’s the code:

float x, y, wd, ht;

void setup ()
{
size (800, 500);
smooth ();
background (225,246,249);
x = width* .5;
y = height* .5;
wd = width* .30;
ht = height* .30;
frameRate (8);
}

void draw ()
{
noStroke();
fill(234, 247, 249);
ellipseMode (RADIUS);
ellipse(width/2, height/2, 210, 210);
noStroke();
fill(166, 217, 237);
ellipseMode(CENTER);
ellipse(width/2, height/2, 250, 250);
noStroke();
fill(171, 219,239);
ellipseMode(CENTER);
ellipse(width/2, height/2, 230, 230);
noStroke();
fill(194, 226, 239);
ellipseMode(CENTER);
ellipse(width/2, height/2, 210, 210);
noStroke();
fill(255, 255, 255);
ellipse(width/2, height/2, 100, 80);
noStroke();
fill(199, 220, 242);
ellipse(width/2, height/2, 100, 83);
noStroke();
fill(196, 217, 246);
ellipse(width/2, height/2, 35, 35);
noStroke();
noSmooth();
point(260, 650);

}

void mousePressed()
{
stroke (222, 199, 239);
strokeWeight(16);
noFill();
ellipse (width/2, height/2, 35, 35);
stroke (118, 119, 118);
strokeWeight(5);
noFill();
ellipse (x+.2, y+.2, wd*.2, ht*.2);
stroke (168, 168, 168);
strokeWeight(8);
noFill();
ellipse (x+.1, y+.1, wd*.1, ht*.1);

}
void keyPressed()
{

if ( key == CODED )
{
if ( keyCode == DOWN )
{
y = y – 5;
}
else if (keyCode == CENTER )
{
y = y + 5;
}
else if (keyCode == UP )
{
x = x + 5;
}
else if (keyCode == LEFT)
{x = x – 5;}
}
}
void mouseReleased ()
{
wd=random (100, 200);
ht=wd;
}
