ROTATE curve

Sorry for the double-posting, but the first one got mixed up with the smilies...
--------------------------------
Hello guys,
I'm new here and with proce55ing and I have a ?:
I've created a smily face  that I have to turn into a frowny face  . What is the easiest and shortest way to rotate the mouth, if it is created with verteces and the "mouth" variables are dependent on the "head" variables?
BTW, how can I fill the mouth or create a "moon" shape ) , so that I won't have to use verteces?
//Mouth position dependent on head position
stroke( 255, 0, 18 );
//lower lip
beginShape(LINE_STRIP);
bezierVertex(head_y+head_size/4.3, head_y+head_size/1.45);
bezierVertex(head_y+head_size/3, head_y+head_size/1.05);
bezierVertex(head_y+head_size/1.55, head_y+head_size/1.05);
bezierVertex(head_y+head_size/1.28, head_y+head_size/1.45);
endShape( );
//upper lip
beginShape(LINE_STRIP);
bezierVertex(head_y+head_size/4.3, head_y+head_size/1.45);
bezierVertex(head_y+head_size/3, head_y+head_size/1.15);
bezierVertex(head_y+head_size/1.55, head_y+head_size/1.15);
bezierVertex(head_y+head_size/1.28, head_y+head_size/1.45);
endShape( );
---------------------------------------------
One more thing:
When I change the size and the position of the head, the smile changes its place and size too and on the right place. However, if I write the position like
ellipse(50, 70, 120, 120);
and not like
ellipse(50, 50, 120, 120);
the position of the smile is not where it's supposed to be. I know it has to do with the dependent vars, but I cannot seem to figure out where exactly is my error...
Any advice will be of help!
Thanx in advance,
KaTe

If you did it like this:
Code:
float s = 50;//size
float x = 200;
float y = 200;
void setup(){
size(400,400);
stroke( 255, 0, 18 );
strokeWeight(2);
}
void draw(){
smile(0, 50, 10, 30);
smile(1, 50, 50, 30);
smile(2, 50, 100, 30);
}
void smile(int c, float x, float y, float s){
if (c == 0){
//moon face
beginShape(POLYGON);
bezierVertex(x-(s), y);
bezierVertex(x-(s), y+(s));
bezierVertex(x+(s), y+s);
bezierVertex(x+s, y);
endShape( );
}
if(c == 1){
//smile
beginShape(LINE_STRIP);
bezierVertex(x-(s), y);
bezierVertex(x-(s), y+(s));
bezierVertex(x+(s), y+s);
bezierVertex(x+s, y);
endShape( );
}
if(c == 2){
//upturned
beginShape(LINE_STRIP);
bezierVertex(x-(s), y+(s));
bezierVertex(x-(s), y);
bezierVertex(x+s, y);
bezierVertex(x+(s), y+s);
endShape( );
}
}

It's pretty straight-forward. But I imagine you're trying to do something wierd and pretty by deriving your "x" co-ordinates from the y ones. It's a different approach at least.
