From Script to Screen: Fortune Telling Machines Influence Map
I picture every machine in the factory having a different design; some with elaborate decorations, some without. I looked at miniature see-saws for ideas for what the see-saw device the crystal ball sits on will look like, but will have to begin drawing to decide on a definite design. I am unsure yet if the main machine my story is based around will have much decoration, or be very simple. As for the mechanical fortune tellers inside the machines, I feel they should also all be different, but not quite as elaborate as the ones that exist in the real world.
