Good video. I think the music at 1:30 is by John Baker of the BBC Radiophonic
Workshop however. There seems to be more information about the machine
publicly available (pictures and video via a Google search) since the last
time I checked.
I've had a play about with a similar idea to Oramics with my synthesiser and
oscilloscope. Here's a sample:

I still don't know how this could be controlled by 35mm film. The best I can
think of is a few phototransistors arranged like you would find in a paper
tape machine. This wouldn't produce free flowing changes in voltage. but would
move up and down in steps. So I don't know. The other option is to have one
CRT per tape, but I don't think it was done that way either.

You run it through a slew limiter.

If you haven't seen it, this interview with the designer/builder
describes roughly some of the techniques they used (more depth would
nonetheless be nice):

Made their own phototransistors by exposing ordinary transistors to
light. The film was used for several things, in both analog and
digital modes.
(warning: the writer also make some strange statements like:
"continuously variable volume controls did not exist in 1965!" !)
