This looks similar to what the cool couple at 100 Rabbits [1] are doing with Uxn. Overall, I love to support anyone producing hobby / cute software (especially with Lua!).
The fact that they seemingly write all this stuff from a sailboat makes it even cooler.
Last I checked it was mostly solar-powered too. That's pipe-dream stuff.
I want to thank you. Your comment sent me down an hours long rabbit hole (pun intended) last night into their collective and I've frittered away many more this morning pricing out sailboats I can't afford! Thank you so much <3

Potato (which uses Uxn) is even more similar to Picotron in that it's like a little desktop environment:
