Rotate coding

The roataion coding which can be implemented on the globe which is on the first place:

float angle;
float jitter;

void setup() {
size(200, 200);
smooth();
noStroke();
fill(255);
ellmode(CENTER);
frameRate(30);
}

void draw() {
background(102);

// during even-numbered seconds (0, 2, 4, 6...)
if (second() % 2 == 0) {
jitter = random(-0.1, 0.1);
}
angle = angle + jitter;
float c = cos(angle);
translate(width/2, height/2);
rotate(c);
rect(0, 0, 115, 115);
}
