Here is an Envato sales notification system with a twist!

Here’s a video:
For those interested in building this: the DMD ’s are available here (you can connect them together to make a larger display) and the Arduino used here is an EtherTen (any network enabled arduino will do) and this is all powered by a PoE injector (so you only have to run a single network cable to wherever the unit is mounted).
Here’s the code on github
