The animation looks really neat but I did not find it very helpful from an pedagocical perspective which is why I built an alternative version inspired by OP. [1]
/edit: I just noticed the OP is built by andrestaltz with Cycle.js. Cycle is a really nice reactive programming js framework that is very great to work with.
