PARALLAX on the S2 LED Dot Matrix Printer

The alignment of Pass One and Pass Two is still not perfect, but here is "PARALLAX" (had to keep up with my friend Carol!) on the Parallax S2 LED Dot Matrix Printer. Photo, Letter Diagram and time-lapsed video attached below. A new thread with all the documentation will be up soon at the Parallax Forums.  Update: This whole process in not documented more fully (with code) over at the Parallax Forums here. Photo exposure time was about 1 minute and 30 seconds.
