Introduction

For HAR2009 we had build a 14 segment board (max to use on Arduino).
The board was able to retrieve messages from http://www.randomdata.nl/goofy/goofy.php and display the letters piece by piece.
There is still a log of all the messages but the board is now down, probably we will use it on other conference like Brucon

The Arduino code

Don't look at my programming skills, it works but it can use some adjustments
