Auto Element tracker Concept (prototype 1.0)

The concept is derived from a marble machine linked here:

I want to make tracking the elements a fun aspect to look forward to rather than forgetting about it. I have made a potentially somewhat working prototype. I would like a more satisfying version where you pressed a lever and incorporated gears and or spring action for a better smoother feel, but I lack the skill.

Also:
I reversed the element orientation so time progresses from left to right.

I'm trying out some options to make waning look cooler.

Future upgrade:
I'd like to add a mechanism that lets me deplete or activate a single element at a time. I think it would work like the screwball scramble game, popping the element to the right spot.
