MobileWill built this LED Matrix link project for his wedding:
i just wanted to share my latest project for my wedding but i have also listed on tindie. I made a easy way to use the led matrix with the max7219. They are daisy chainable and i will be making a microcontroller add on as well. So it will be everything you need to control led matrices.
The plan is to have it at my wedding and to have guests send messages to it.
