I have to say, its nothing too hard do what i did, but in actions is pretty cool 
I have taken the SoftwareServo lib ( Arduino Playground - HomePage ) edited a bit and it can control servos attached on a Shift register (http://arduino.cc/en/Tutorial/ShiftOut )
Tested on arduino IDE 0022
Video:
Lib attached on the topic.
This is an example:
#include <ShiftOutServo.h> //Just including
#define latchPin A0
#define clockPin A2
#define dataPin A1
//I am using analog pins vbut you can also use digitals...
byte pins[] = {latchPin,clockPin,dataPin};
bool originalData[] = {0,0,0,0,0,0,0,0}; //The [0] and [1] is for servos
ShiftOutServo servo1;
ShiftOutServo servo2;
void setup(){
pinMode(latchPin, OUTPUT);
pinMode(clockPin, OUTPUT);
pinMode(dataPin, OUTPUT);
servo1.attach(0);
servo2.attach(1);
}
int the_angle = 0;
long int timett;
int adding = 2;
int bgn = 2;
void loop()
{
servo1.write(the_angle);
servo2.write(180-the_angle);
//Shifting some leds...
originalData[bgn] = 0;
bgn++;
if (bgn == 8){
originalData[7] = 0;
bgn = 2;
}
originalData[bgn] = 1;
//Its nice do it to reduce noise...
timett = millis()+10;
while(timett >= millis()){
ShiftOutServo::refresh(pins,originalData);
}
the_angle= the_angle+adding;
if (the_angle >= 180 || the_angle <= 0 ) adding = adding*(-1);
delay(10);
}
