Somewhat random, but spreadsheets continued to evolve after VisiCalc (obviously).

Here is one by the inventor of VisiCalc, Dan Bricklin, on github: https://github.com/DanBricklin/socialcalc

Audrey Tang (who happens to currently serve as the Minister of Digital Affairs of the Republic of China (Taiwan)) created the Node.js port of SocialCalc, EtherCalc: https://github.com/audreyt/ethercalc

Audrey made a fascinating write up of SocialCalc for The Architecture of Open Source Applications https://aosabook.org/en/v1/socialcalc.html

  book for parents and kids.

That looks seriously cool. Just the colors give me goosebumps :)

completely offtopic:

My dream is to build a super cheap child friendly computer, that the kids can build themselves, has a software keyboard that directly polls the gpio pins so that kids can modify their keyboard instead of having a keyboard controller (just so there is less mistery in what happens when a key is pressed). And the OS is something inspired from LEAP: https://www.youtube.com/watch?v=o_TlE_U_X3c that allowing you to evaluate code and apply it to your current file. A bit like your LOAD81 but with text.

I have a prototype now: https://github.com/jackdoe/programming-for-kids/blob/master/... but it has a long way to go.
