    private var rotAngle : float = 0;
    private var pivotPoint : Vector2;

    function OnGUI () {
        pivotPoint = Vector2(Screen.width/2,Screen.height/2);
        GUIUtility.RotateAroundPivot (rotAngle, pivotPoint);
        if(GUI.Button(Rect(Screen.width/2-25, Screen.height/2-25, 50, 50),"Rotate"))
            rotAngle += 10;
    }
