In my "focal points" for a STEM curriculum (stealing jargon from NCTM
of that day), I included Mandelbrot Set for one of the four.
I deliberately chose what I'd call "complex topics" i.e. when you zoom
in, you get lots of detail, could go on for hours (but don't have to).
Like another of the four was Pascal's Triangle, which fleshes out to
Pascal's Pyramid and more -- all sorts of number patterns there.
Back to fractals, they've continued to explode and lots of work has been done.
Computer science has help make computational thinking an experimental
exercise, complete with feedback loops, lots of trial and error.
What would be the equivalent of the Mandelbrot Set in volume (I'll
deliberately not say "in three dimensions" for reasons of my own).
Interestingly, the aesthetic quality of having lots of rich and varied
detail no matter how far one zoomed, was the key filtering criterion,
so candidate "3D Mandelbrots" were dismissed on aesthetic grounds.
An offshoot or branch in this research is what's now called the
Mandelbulb, a discrete / specific shape one could come to recognize
much as the flat 2D shape has become familiar.
Here it is:

The software for generating and filming such beasts is out there, and
I'm trying to work backwards from an environment that's at least
conducive to playing with such tools.
They're downloadable legally free of charge in many cases. Mainly one
just needs an excuse, a set aside social time, for using tools of this
genre.

Ideally, that's where schools come in, whereas in practice we often
make it less practical to play in this way, by herding kids and to
buses and taking them away from their on-line university connection.
Adults don't get any time either but that should change, as
"retirement homes" prepare for those geeks who'd like nothing better
than to tinker with Linux for hours.
Anyway, that's an example of a foray which would need to be backed up
and reinforced other other kinds of hands on activities, such as just
playing with complex numbers interactively.

The idea the public schooling might also be a function in the home
environment is not new: it's called homework.
More homework of this kind, with guardians encouraged to set aside a
study space in the house, and/or provided as community spaces, like
coffee shops, is what to expect.
