Kudos! I love seeing things people have built for their kids.

This reminds me a bit of this site, which has been around for a long time and has a similar motivation: teach physics concepts using simulations:

Not the same level - but teaching my kid to use keyboard, and i vibecoded this: https://ai.studio/apps/drive/1MErVnhhK89peNh1RPa3y-ufFExG5Bn...

		In case anyone else was curious, `ai.studio/apps` apps apparently require a google account login by default. Google ai-mode says allowing public access is an author option, but then (1) API costs are borne by the author, and (2) there are some (unclear) compliance implications.

		This is cool! I'm curious whether you're using this to teach initial familiarity, or as the first step toward touch typing? For touch typing, I think Typing Club is a good place to start for kids. And then Keybr to develop full fluency. And then Monkeytype to develop speed. EDIT - when I wrote this comment I had only opened the link on my phone. Now I see it on desktop it's clear that the on-screen keyboard is intended to teach key positions without the user looking down at their keyboard. It's good.
