Wow! That is very cool. I'd love to see a more detailed write up or video about that system. I really miss that era of multimedia. So much of it seems hokey and awkward in retrospect but I feel like there are lots of unfinished thoughts and experiments in that realm that are only starting to be revisited now in the AR/VR/experiential context.

I thought my elementary school was pretty baller (it wasn't -- especially in comparison!) because its library had an LD player which got pulled out once or a year to show the same space race video -- complete with frame indexing and crystal clear frames on pause. Until I bought one for myself in the 2010s, that was only one of two times I saw LD players in the wild.
