I thought some of you might be interested in the new release of my package, lentic. One of the things that it now does is allow multi-modal of editing of Emacs source, using org mode for the documentation. I realise that it's already possible to use ELPA org-babel to write literate el files, or to use outorg.el, but lentic provides a different form of interaction. You can edit the org form or the emacs-lisp form as you choose. The source code of lentic is, itself, written in this way. There is a screen cast linked below which shows what the interaction looks like.
