Another take on the same idea. The ones that I had used a long strip

ratchet stepping system. Heavy buggers because of the steel case on
each module.
I suspect that there were many variations on the idea.

e.g.: http://www.cs.ubc.ca/~hilpert/e/edte/VennerTSA3336/index.html I liked the mechanical project-type display,
where a stepping
arrangement moved a strip of film.
I've never seen that kind, but it sounds very cool! The projection
displays I've seen use an array of twelve incandescent bulbs, film
with a corresponsing array of twelve glyphs to act as masks, and a
plastic molded piece that provides twelve lenses.
