RGB LED Coffee Table Colorduino Questions

Projects General Guidance
1

Alright so I am in the midst of building an RGB LED Coffee table and I just bought the 128 leds I will need to build it along with the wrapping wire etc... I just had a few questions as I am new to arduino.

First I am getting two Colorduinos so that I can control both of my 8x8 matrixs. My first question is do I only need the Colorduino shield or do I also need an arduino aswell to run it?

Here is what Im looking to buy

Since the shield can only control an 8x8 matrix I plan on buying two, 1 to control each matrix as my table will be 8x16. I've only seen this done using an 8x8 and 1 colorduino, so how would I combine the two to be able to communicate?

Hope my questions arent to confusing

Thank you

I have had a lot of fun making 16 x 8 displays using an Arduino and two Colorduinos.
I decided to use I2C to communicate with the Colorduinos.
Nick's I2C code is here:
http://code.google.com/p/colorduino-i2c/downloads/list
There is a program to upload to each Colorduino to set their addresses. Then the main code for the Arduino.
Contact me if you need help.
