Jist is a new Javascript-based Lisp interpreter currently in development as a research project at Stewdio. With less than 24 hours behind it, Jist is in an “über alpha” stage—offering only minimal functionality and very little stability. The core of Jist is currently a cribbing of Joe Hanley’s JavaScript Lisp Interpreter. Stewdio is rebuilding this to favor lexical closures over dynamic scoping, and to add avenues for DOM manipulation.

Suggestions and code submissions welcome. See Jist at http://stewdio.org/jist/.
