I like massages! Some times, after a long days surfin' (on the web ;) ) I like to have my wrists and back massaged.

Text massages not so much.

HOWEVER text messages are a different story. They can be quite informative.

For this you will need microController programming skills.

Do you have a micro you prefer to use? PIC, AVR, TI?

Google "led message scrolling circuit" gives a few tens-of-thousands of results.

The first for using existing signs and just building a driver:

The second from MAXIM, being pretty good:
