Urbit is probably one of my favorite things. The language is insane. The base virtual machine it runs on is insane. The entire stack rewrites everything for the sake of doing everything perfectly. It redefines whatever it wants. And somehow, it's actually usable.
Hoon is a programming language that uses two-character runes instead of reserved words. It's purely functional and vaguely Lisp-like. It compiles down to a minimal combinator-based virtual machine built entirely out of cons cells and bignums, where the only operator is addition. And yet throughout all of that, it's actually possible (and scarily easy) to code in, and I'm somehow fluent in it. That kinda scares me.
