I see this to be hugely practical. It will enable rapid charting in source code documentation, and also, solve the table formatting problem once and for all.
Edit: shapes? Patterns? Gradients? Dithering? (Think about cacao) lasso tool? Semantic movement? Like, w moves over all reddish blocks
Also I love the idea of semantic movement, I'll definitely put it on my feature-list!
Even if we go with monochrome charts, it will be super useful for describing data structures and visualizing algorithms.
Also, looking forward to the semantic movement implementation!

Jokes aside, maybe you can use that for inspiration :)
I'm wondering if artist-mode can be used as a minor mode? Charts everywhere :)
Cool idea to use %/* (or similar) to rotate/flip stuff! I only thought about replacing a certain color with another using %s/
