Ayah Bdeir used an Arduino with a custom Firmata firmware to run a  
shift register and a matrix of LEDs.  The code and the circuit is here:


A little bit of work needs to be done to add shift register support to  
the Pd side of Firmata (Pduino), but I'd be happy to do it if you'll  
use it.  Its already on my todo list.
