Modulo. The modulo operator (%) returns the remainder of a number divided by another. As in this example, it is often used to keep numerical values within a set range. 

  
   
  int num = 20;
  float c;
  
  void setup()
  {
    size(200,200);
    fill(255);
    frameRate(30);
  }
  
  void draw() 
  { 
    background(0);
    c+=0.1;
    for(int i=1; i<height/num; i++) { 
      float x = (c\%i)*i*i;
      stroke(102);
      line(0, i*num, x, i*num);
      noStroke();
      rect(x, i*num-num/2, 8, num);
    } 
  }
