...alternatively, if you have a look at the article and some of the
articles lined from it, you get to see trippy mathematical drawings! :-D

There's a whole world of Seriously Interesting Stuff out there -
inverses, evolutes, envelopes, caustics, epicycloids, pedal curves...
it's pretty mental stuff!

It should be possible to draw a nephroid with Spirograph, yes. (A
nephroid is a type of epicycloid, and Spirograph draws epicycloids.)
A nephroid is one specific curve in a very large family. I posted that
link because I liked the name, and because many rather interesting
articles are directly reachable from it.
