This is an excellent project! Congrats and thanks for sharing! (LLM writing notwithstanding)

I wonder if it would be a good base to create a kids phone / yogurt-cup telephone: no screen, no keyboard, just a box and figurines, and to call someone up you put the figurine on the box. It could be boxes-only (only people with a box can call or be called) or it could be more general: kids only have boxes and figurines, but the machine is able to call actual phones.

I think even as an adult I would enjoy that.
