I had heard of interactive C++ before, but to see it, and see it in a Jupyter notebook, was eye-opening.

Maybe you also would like to see the Energize C++ environment created by Lucid, after they pivoted away from Lisp Machines.

I did, but while it looked like a nice IDE (as an aside, I was a Lucid Emacs user), what amazed me about the Jupyter example was the interactive C++ interface with GUI display of objects.

Yes, that is pretty neat.
