I ctrl+f'd for org-reveal, and didn't find it so I'll give it a plug.

I write org-mode files (kind of like a richer version of markdown), and use org-reveal and emacs' publishing system turn them into slide shows like [1] this: (pic: [2]). The best part about the workflow is including code snippets using org mode's add source block, which allows me to edit code in the usual mode that I edit code with. Also org-reveal uses emacs' code highlighting settings to do code highlighting.
