Thank you for not creating cycloid content!
(In my denomination we celebrate on the twenty-second of August, how weird is that?)
Then who did create it?
(The superior date format is YYYY-MM-DD)
Zorgit made this one for Wikipedia for example.

Yours is a sinusoid, but looks like it could have been a cycloid.
(ISO8601 is life)
explain why the red line is not the same as the line in the original content, if the circles are moving the same way
Tricky, right?
It's because there is "friction" and the part of the circle touching the line can't move relative to it, and so you get that "cusp" shape.
Maybe someone else can give a better explanation, I haven't had any coffee yet.
oh right, i see it now. in the original post, the line goes through the ball! thanks!
