The only thing a video could show better than a picture is the animation. But it is really only a simple and boring vertical scroll animation, maybe you are expecting a little too much here. You won't put this on your desk and watch it instead of a movie (except you are incredibly excited about the exchange rate anyway  ). So right now I think I am too lazy to do a video for just that. Also there are videos of such message boards on Youtube already, just search them.

The base program (and therefore also my plug-in) is based on .NET which means it should be possible to run it using the Mono framework on Linux as well as a Mac. However, I haven't tried, so far I only tested it on Windows.
A quick search came up with this so apparently it is possible to run Mono on a Raspberry PI though I think it's a lot of overhead for the poor small thing. Also it is a GUI application so you will need to run a desktop environment on it.
Regardless of that if I find the time I will do a test with my board on Linux and report the results here.
