On my model people could look through a peep hole at the top to see a Lego “film” play as they turned a crank on the side.

Here you can see it with the top off with the Lego “film” (black and white).

My “filmstrip” was made of Lego with 12 frames showing a white line going from one side to the other.

When people saw it play it gave a very good illusion of how it was to look at a motion picture in a “Kinetoscope”

I made cranks on both sides of the model, so it could be used by both right and left handed students.

It was a very popular display!
