how to control 64 servos with arduino?

Hello everyone.

I am working on a project where I am planning to use 64 servos that track the motion of a mouse and they operate according to the x and y position. Until now I have made a sample with 8 servos in a row, and using Processing I am feeding with data my arduino uno. However, going to 64 servos looks scary to me. Do I have to use 2x arduino uno + 2x 32 servo shield or should I switch to arduino mega? Is there any other alternative?

Here is a 32 servo shield that I have found: http://www.ecrater.co.uk/p/15329910/arduino-sensor-shield-v50-expansion?gps=1

Stacking Shields

Hey everyone,

I have a quick question concerning stacking arduino shields. Can you stack as many shields as you want as long as none of them use the same pins? 

I have Ro-Bot-X's robot builders shield as well as a xbee shield that I would like to stack onto an Uno. From my understanding, the xbee shield just uses pin 0 and 1 for serial and breaks out the rest. And then the robot builders shield doesnt touch pins 0 or 1.
