Impressive demo. Runs on MacOS, Linux [edit: not Windows? edit3: yes, Windows] can also run on an emulated machine. Project link [1]; commits go back 10 years.
[edit:] Plenty of unusual, sophisticated architecture. Multi-thread/-CPU/-computer mesh. Assembly-level object system. "Register juggling for parameter passing is eliminated by having all functions define their register interface and parameter source and destinations are mapped
automatically using a topological sort. None DAG mappings are detected so the user can break them with a temporary if required."
[edit 2:] Curse you, I've got other stuff I should be doing.
