Rotating a square around the Z axis. * To get the results you expect, send the rotate function angle * parameters that are values between 0 and PI*2 (TWO_PI which is * roughly 6.28). If you prefer to think about angles as degrees * (0-360), you can use the radians() method to convert your values. * For example: rotate(radians(90)) is identical to the statement * rotate(PI/2). In this example, every even numbered second a jitter * is added to the rotation. During odd seconds, rotation moves CW and * CCW at the speed determined by the last jitter value.
