Genius! Was this an original idea or adapted from elsewhere? Any plans to automate the ¢ to minute ratio when your 9yo begins to establish quarter wealth?
I haven't seen anyone doing the same or similar thing. I only did it because I thought it's gonna be easy to implement. It wasn't too easy, but it was a lot of fun.
I also made the Unity app to support 3D animations, and I'm planning to improve it. For example, it's easier to explain what "30" is with 3 rows of 10 balls (each row is 5 + 5). Animation for subtraction is different, I experimented, added 3D kittens running around, VFX effects, and so on. So kids also have a visual representation of math operations.
I'm ready to share/demonstrate the implementation to folks in South San Francisco or nearby. I would even Open Source it if there is enough interest, but can't guarantee it's gonna be super quick without some help from interested enthusiasts.
In the future I'm planning to improve math engine and visual part, so it's easier to understand what math is. There are many ideas on how to automate, since coin dispenser and acceptor support all kinds of coins.
