We use the
reveal.js toolkit by Hakim El Hattab. It creates really nice-looking, theme-able CSS and JavaScript-based presentations. As we found out with MORE, outliners make excellent authoring tools for presentations. As with MORE, all the technical details are taken care of by the software and a template. You get to craft your presentation in an outliner. You really can get the thought perfect, and the formatting "just works" -- takes care of itself.
