Ich hab meine Code soweit erweitert, dass der Mauszeiger den "Punkt" darstellt, zu welchem sich die Zeichen durch Rotation orientieren.

int     anzahl = 7;
int     rand = 50;
float   xStep;
float   yStep;
float   rot,rotx,roty;
int[]   permutationsIndexList = {
  0, 1, 2, 3, 2, 1, 0,
  1, 2, 3, 4, 3, 2, 1,
  2, 3, 4, 5, 4, 3, 2,
  3, 4, 5, 6, 5, 4, 3,
  2, 3, 4, 5, 4, 3, 2,
  1, 2, 3, 4, 3, 2, 1,
  0, 1, 2, 3, 2, 1, 0
};

void setup()
{
  size(600, 600);
  smooth();

  xStep = (width - 2 * rand) / (float)(anzahl-1);
  yStep = (height - 2 * rand) / (float)(anzahl-1);

  //noLoop();
}

void draw()
{
  background(255);

  int     permutationsIndex = 0;

  pushMatrix();
  translate(rand,rand);
  for(int y=0; y<anzahl;y++)
  {
    pushMatrix();
    for(int x=0; x<anzahl;x++)
    {
      rot = atan2(((mouseX-xStep/2) -(x*xStep)),((mouseY-yStep/2) - (y*yStep)));
      drawPermutationObj(permutationsIndexList[permutationsIndex],rot);
      print(str(permutationsIndexList[permutationsIndex]) + "\t");

      ++permutationsIndex;

      translate(xStep,0.0f);
    }
    println();
    popMatrix();
    translate(0.0f,yStep);
  }
  popMatrix();
}

void drawPermutationObj(int type, float rot)
{
  pushStyle();
  pushMatrix();
