Thank you for sharing that context, it makes a lot of sense. I had no idea about the "massive banks of slide projectors" thing either, as far as I knew slide projector technology had never advanced beyond it being the thing annoying people use to make you sit through their vacation photos. That's very interesting.

The funny thing is that the basic projector didn't advance technically. They just found a way to multiplex them into something larger. Like taking a single LED and figuring out how to make a video wall.
