The tautochrone property is really neat to see. It's also fascinating that there are these connections to geometry and physics: the rolled circle cycloid describes the path light would take through a medium which becomes continuously denser.

I wonder if atmospheric density could make light follow a (not incomprehensibly large) cycloid.

I also recommend the 3blue1brown channel, he has wonderfully visual and intuitive explanations of mathy concepts.
