camera kiosk/booth video thingy

i've got a music gig this friday at a big posh event in a club.
while i'm not playing i want to set my computer facing the crowd with a webcam on top so they can come and have a look on screen, the script i've written (adapted from someones example somewhere on the web) takes a snapshot every couple of seconds and displays it to screen... along with a few other visuals.
i want to save these shots and upload them onto a website the next day, problem is save() and saveFrame() only save the entire window (in this case 1024x800) - all i want to save to a file is the video capture at 160x120.
is there any easy way of doing this like save.video() or something, a quick answer would be much appreciated as this needs to be ready for friday am.
Code:
// fishy fishy video
int cx = 0;
int tmr = 0;
int ex = 0;
int elSize = 10;
int ceSize = 7;
BFont metaBold;
void setup()
{
framerate(90);
size(1024, 800);
background(0);
noStroke();
beginVideo( 160, 120, 30 );
metaBold = loadFont("RotisSanSer.vlw.gz");
textFont(metaBold, 40);
}
void loop()
{
//-------------------------------------------------------------
for( int a = 0; a < 65 ; a++)
{
int rowndx = int(random(23));
int x = int (rowndx * 10);
int rowndy = int(random(56)+24);
int y = int (rowndy * 10);
color c = video.pixels[ (x/8) + ( (y/8) * video.width ) ];
fill( c );
rect( x, y, ceSize, ceSize );
}
//-------------------------------------------------------------
for( int a = 0; a < 300 ; a++)
{
int rowndx = int(random(50)+23);
int x = int (rowndx * 10);
int rowndy = int(random(56)+24);
int y = int (rowndy * 10);
color c = video.pixels[ (x/8) + ( (y/8) * video.width ) ];
fill( c );
rect( x, y, elSize, elSize );
}
//-------------------------------------------------------------
for( int a = 0; a < 65 ; a++)
{
int rowndx = int(random(23)+73);
int x = int (rowndx * 10);
int rowndy = int(random(56)+24);
int y = int (rowndy * 10);
color c = video.pixels[ (x/8) + ( (y/8) * video.width ) ];
fill( c );
rect( x, y, ceSize, ceSize );
}
//--------------------------------------------------------------
image(video,ex,0);
ex = ex+1;
if (ex > width){
ex=0;
}
tmr = tmr +1;
if (tmr >50){
noFill();
stroke(55);
rect(ex, 0, 160, 119);
image(video, cx,122);
saveFrame("sshot-####.tif");
noStroke();
delay(320);
cx = cx +160;
tmr = 0;
if (cx > 900){
cx=0;
}
}
smooth();
fill (255);
text("COME AND SAY HELLO, we'll put your picture on hippocamp.net", 150, 270);
}

oh, if you run that code be sure to comment out the saveFrame() line... unless you want a directory full of images 
thinking about it wouldn't saveFrame(x, y, width, height) be a really useful addition to the syntax?
