Agreed! I'm confused by the number of comments that suggest this was a waste of time because other potentially similar implementations exist. There could be a hundred of these and I'd still be interested in looking at them.

Disregard those comments. There will always be critics wondering why you don't just use floppies taped to a carrier pigeon instead of email. We are nerds.

When I was young, I was taught that Benjamin Franklin taught himself to write well by reading a work, and then trying to rewrite it from memory.

I imagine a similar principle is in play here.

There's value in rewriting what already exists and works, even if it will only ever be useful to yourself.
