Aufgabe: Durch Bewegen der Maus sollte sich die Permutation verändern. Mithilfe der reference habe ich einen Farbwechsel mit "mouseMoved" erstellt, dementsprechend gross ist die Freude:

int     anzahl = 7;
int     rand = 50;
int     value = 0;

float   f = 0;
float   xStep;
float   yStep;
int[]   permutationsIndexList = {0, 1, 2, 3, 4, 5, 6,
                                 1, 2, 3, 4, 5, 6, 5,
                                 2, 3, 4, 5, 6, 5, 4,
                                 3, 4, 5, 6, 5, 4, 3,
                                 4, 5, 6, 5, 4, 3, 2,
                                 5, 6, 5, 4, 3, 2, 1,
                                 6, 5, 4, 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++)
        {
          f += 0.1;
          drawPermutationObj(permutationsIndexList[permutationsIndex],f);
          print(str(permutationsIndexList[permutationsIndex]) + "\t");

          ++permutationsIndex;

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