hi

i have a simple applet that divides the environment into squares and colours each of them randomly. I'd like to reflect the colours used in top half in the bottom. This is my code at the moment:

Code:

for (int i = 0; i<COLUMNS; ++i) 
  {
	for (int j = 0; j<ROWS; ++j) 
	{
	    p[j] = new Pixels(i * TILE_WIDTH, j * TILE_HEIGHT);
	    p[j].draw();
	    p[j].animate(); 
	}
  } 

and the draw and animate functions are as follows:

Code:

  void draw()
  {
    //
    rect(x, y, TILE_WIDTH, TILE_HEIGHT);
  }
  void animate()
  {
    int red_random = (int)random(255);
    int green_random = (int)random(255);
    int blue_random = (int)random(255);
    fill(red_random, green_random, blue_random);
  } 

I've tried a few different methods, along the lines of width-x and height-y to duplicate, but I can't get anything to work. My goal is to have 4 fold symmetry, but I would be happy with x2 atm
