Mike and I expanded on my Highlights project last week and came up with this. I’m still not sure why it’s taking so long to play.

//global variables
int ballWidth = 10;

Circle myCircle;
Circle circle2;

void setup()
{
  size (600, 600);
  smooth();
  background(0);
  //frameRate(30);
  myCircle = new Circle(10, 400, 10);
  circle2 = new Circle(590, 200, 10);
}

void draw()
{
  background(0);

  //draw colored balls
  for (int i=0; i * ballWidth < width; i++)
  {
    for (int a=0; a * ballWidth < height; a++)
    {
      int ballX = ballWidth*i + ballWidth/2;
      int ballY = ballWidth*a + ballWidth/2;

      fill(map(ballX,0,width, 0,255), frameCount, map(ballY, 0, height, 0, 255));
      ellipse(ballX, ballY, ballWidth, ballWidth);
    }
  }

  //determine coordinates of the highlights
  /*float column = random(0, width/ballWidth);
  int newColumn = int(column);
  int randomX = newColumn * ballWidth+ ballWidth/2;
  float columnY = random(0, height/ballWidth);
  int newColumnY = int(columnY);
  int randomY = newColumnY * ballWidth + ballWidth/2;*/

  //draw highlights
  //drawHighlight(randomX, randomY);
  //drawHorizontalHighlight(randomX, randomY);

  myCircle.moveIt();
  myCircle.showIt();

  drawHighlight(myCircle.x, myCircle.y);
  drawHorizontalHighlight(myCircle.x, myCircle.y);

  circle2.moveIt();
  circle2.showIt();

  drawHighlight(circle2.x, circle2.y);
  drawHorizontalHighlight(circle2.x, circle2.y);

}//end draw

void drawHighlight (int _x, int _y)
{
  for (int d=0; d*ballWidth <= width; d++)
  {
    //bottom spoke
