I just wanted to reply by saying that this code has helped me immensely, although for much different purposes.

New question, related to this code:

How would one make it so the green dot "swings" from one extreme of the disc to the other?

Edit: So far, this is the closest I can get:

Code:

  if (going) {
    //speed of movement
    pos += 0.1; // Change value to modify speed
    circleX = int(centerX + 0.5 * diskW * sin(pos));
    circleY = int(centerY + 0.5 * diskH * cos(pos));
    if(circleX > centerX + 20) {
	pos = pos + accel;
	accel = accel - .005;
  }
    if(circleX < centerX + 20) {
	pos = pos - accel;
	accel = accel + .005;
}  
}


It swings to the right exactly as intended, but upon changing direction it tweaks out.
