I love karsten and have been following his work for a long long time. Used/Use his old toxiclibs library extensively both in processing and java. Have ported parts of it to golang for personal use. I want to say he also had some librarys for openframeworks/c++ and I probably used those as well (it was perhaps someone elses rough port of toxic to c++).

Originally I bounced off this because of clojure, it just wasn't worth the time to learn. Now it's typescript.. another language I'm just not interested in learning. I'm happy to port whatever bits of the library I want to use to a language I prefer when I need it.

But this is a absolutely remarkable set of libraries covering all kinds of nooks and cranies. It's worth putting on everyones list.
