Check out https://sinerider.com/ too! A friend of mine who helps Grant Sanderson sometimes with 3B1B stuff built it, it's an awesome math education game like LineRider but using formulas to build the tracks.
I love both 3b1b and SineRider, both have had more impact on my intuitive understanding of function composition than anything else.
