Hi Josh,
I was involved with some lighting projects that used an XML file as an=20
animation data source. There are XML elements that describe what values=20
to use for each scene and others for optional fade-in, dwell and=20
fade-out times.

I didn't write the parser or actual animation engine for the micro, only=20
the PC software that had the channel/timing grid and did the export to=20
XML. The micro unit outputs the data as a DMX stream, but the overall=20
concept would be the same for pixel drive.

The dimming (over time) commands you talk about are present in the=20
Christmas lighting controllers made by Light-O-Rama.

There is also a Raspberry-Pi based playback engine called the Falcon Pi=20
Player. Not sure on the web site for it but it's mentioned on a few of=20
the Christmas light forums.

Hope that helps.
David...
