That reminds me that there is a simulation tool called lightningpolar that allows you to create a bitcoin network with its nodes, perform mining, have your lightning nodes and much more, all from the graphical interface https://lightningpolar.com/

I saw this teaser too. If it works as good as this looks, it's going to be a huge hit.

This could really help non-technical people like myself learn the high-level aspects of Bitcoin development. Any goals to sell this to different universities across the world to make this part of a university program?
