Very nice! Decades ago (circa 1981) I programmed a stacked array of 16-24 of these driven off of an Audio Visual Labs (AVL) micro-computer. I had used a CP/M-driven AVL Eagle, which was about the same size as the original IBM PC, to sequence two dozen projectors to soundtracks. The first Eagle computers were produced by Audio Visual Labs (AVL), a company founded by Chuck Kappenman in New Jersey in the early 1970s to produce proprietary large-format multi-image equipment. Those computer sequenced projectors driven by the Eagle were used to create massive 40 foot long by 20 foot high rear-projection multimedia extravaganzas for large corporate events. These were stunning, heart-stopping Hollywood-class analog multimedia productions for major corporate events, hosting thousands of employees, years before the emergence of mainstream computer-based multimedia as we know it today, became possible.
