Since the question was raised... as described on our website, the ColorDMD invention is the subject of a pending US patent.

It's based on work I initiated in July 2009 and have spent several years improving upon, reducing to practice, and converting to a viable product that I could contribute, support, and share with the pinball community.

While I'm impressed with David's initiative and work with the Rasberry Pi, I confess to being a little concerned that the posted RgbDmd video demonstrates several of the ideas I disclosed in the patent application, and presented in seminars over the last few years.

I hope that the effort and investment made to invent the ColorDMD and get it to where it is today are considered by others as this new project progresses, and its scope and direction become more clear.
