Dot Matrix Display

I acquired 4 of these Sure 0832 dot matrix electronics boards recently. They were going spare from a project I worked on a long time ago (pre blog). Instead of leaving them in a box and forgetting about them I thought I should turn them straight back round into a new display that we can take along to Maker Faires. A simple laser cut frame holds all 4 displays in place, an arduino nano drives the boards and controls the animation. I'm using Miles Burtons arduino library to control the basic functions but I had to update it for the most recent version of the arduino IDE (1.5.8) so I've included that modified library in with the source files (source here)
