One fun thing about that first tutorial is that it's very accessible to non compsci/math people... because instead of building strings or "objects" or doing math, you're building pictures, live! And DrRacket makes it very easy to get going!
@estebanm Oh I heard about this but couldn't remember what its name was... thanks!
@cwebber I haven't actually used Pollen, but the book Practical Typography I can recommend, it's great if you're into that sort of thing.
@cwebber Do you know Pollen (http://docs.racket-lang.org/pollen/)? It's made by the guy that wrote https://practicaltypography.com/ (and, of course, that book is written in Pollen).
