This is awesome, and could be a fun project for introductory students. It gives practice with:

- Extracting digits from numbers (easily done with a few function calls in Python, or some math)

- Calculating frequency of a known set of items in a sequence

- Some application of simple mathematical formulas[1]

I wouldn't mind trying this at some point...
