Really loved the multicursor/evaluators idea in this one. Check out project here: https://github.com/batman-nair/IRCIS And here's FizzBuzz visualization in this programming language: https://batman-nair.github.io/IRCIS/samples/fizzbuzz.html

Reminds me of Orca: https://github.com/hundredrabbits/Orca

Cool that the visualizer shows execution; lame that it doesn't show all state, but at least it's easy to imagine adding that. Hard to imagine adding such nice execution visualization to other languages. <3 for spatial langs.

Yup, 2D programming is really an under explored area. But one of the twists of history is that one of the very first programming languages was a 2D language: https://en.wikipedia.org/wiki/Plankalk%C3%BCl

From the Wiki, I can't see how that's a 2D language. It looks statement-based to me (which is weird because this is well before the era of the terminal — I'd assume this has some sort of mechanical interface. Though maybe that changed as the language was evolved from the 40s to the 70s)
