 Bigger Bigger  Smaller Smaller  Reset Reset

Hello this is my first post so I hope I've come to the right place.

I have purchased 8 Addressable RGB LED Strips from Sparkfunhttp://www.sparkfun.com/products/10312 and they are a blast!  I have connected them in a chain from 0-255 and wrapped them around to make a matrix.  I only use 2 pins to send the data and every second strip has a 5V 3A supply and a common ground connected to the Arduino.

   0,   1,   2,   --->--- 29, 30, 31  STRIP #1
 63, 62, 61,   ---<--- 34, 33, 32  STRIP #2
 64, 65, 66,   --->--- 93, 94, 95  STRIP #3
127,126,125,---<--- 98, 97, 96  STRIP #4
...                                                  STRIP #5
...                                                  STRIP #6
...                                                  STRIP #7
...                                                  STRIP #8
....... you get the point

I am able to control them without any issues and the brightness is impressive.  The next idea I have is to use this 32x8 "matrix" and make a stock market like text ticker.  I can write text now but it is a very tedious process.  I turn on each LED individually then post the frame to get the text I want. 

Does anyone know a simple way to convert text into a matrix so that I can display it on my strips?

Is there a SMART approach to this problem?

Is there a library that could help me out?

Would using MATLAB help?

Anything that could point me in the right direction?
