OPs function is indeed the Weierstrass function, but the “rollercoaster” here isn’t a function at all, since there are multiple values per element, isn’t it?
Ah my bad, I did not see the comment had a picture attached. There’s probably a mathematical way to derive the shape of the euthanasia coaster as well, but I don’t know.
It’s the Weierstrass function, a function that is continuous but not differentiable anywhere.

maybe it’d be better modeled by a 3d spiral? I’ll hit up Desmos if I remember my polar coordinates right.
