colorForth is, in Chuck Moore's own words: "A dialect of Forth that uses color to replace punctuation. Includes its own operating system. Produces extremely compact programs. Instant compile from pre-parsed source."
several vaguely related projects worked on by me: a 3d engine with a javascript-like scripting language (pdsys); an older scheme dialect (vmsys); ... (2009-04-28: I have been gone for years, may try to put up some newer stuff...).
