KnowOS

project that Mike Travers worked on for 2005 Lisp conference. https://hyperphor.com/ammdi/KnowOS a virtual environment consisting of abstract objects and operations to manipulate them... The central user interface of our current KnowOS is a web-based Lisp Listener and associated dynamic web pages, which users interact with through a standard web browser. (This basically invented the web-repl-notebook UI paradigm, later popularized by Jupyter.)
