*Programming in 2D text*
This evening I'm thinking of two ideas I've thought about several times before, but never together.
The first: Arjun Nair's https://github.com/batman-nair/IRCIS, an esoteric language (art for art's sake) that comes with a cool visualizer. Maybe all languages should.
The second is Dave Ackley's https://movablefeastmachine.org, a tiled processor for very finely grained distributed computation. Programming it is like playing with a cellular automaton.
