StumpWM sort of gets you a dynamic interface. Use the Scheme(ish) shell (http://scsh.net/ http://scsh.net/) and you can get ...kind of dynamic. Then there's the obligatory mention of this guy who took it to the next level http://www.howardism.org/Technical/Emacs/new-window-manager.html http://www.howardism.org/Technical/Emacs/new-window-manager.... Plan9 + ACME had an interesting 'editor/OS' integration, especially for the time, where you could highlight text, invoke a mouse click action, which would send it to a shell, and return the result on a new-line within your editor. Having everything exist as a file with an addressable file descriptor really made the platform powerful (too bad the licensing was horrible until recently). It's not homoiconic as a proper LISP-1 would be but still an interesting approach.
