it's just a matrix (with rows and columns). on each "crossing"
you install device of your choice. Here is something very neat
for all audio freaks (don't remember where I found it):

Hello

There are various LED running message circuits. What exactly are you looking for? How big it will be?

You are looking a Large format Led moving sign:

Do yourself a favour and buy Z8 encore kit for US$49 (check www.zilog.com for details or just go to www.mouser.com and
buy it.)
It comes with 5 character LED matrix and enough memory.
It also includes C compiler with examples, book, power supply,
cable etc.
