Reveal.js

Been around for a good while, but still awesome.

You should check out all his labs on http://hakim.se/

Be ware that most of the stuff there is just PoC and you may have some issues trying to adapt them, but the showcases are awesome :)

Not really. But it's awesome. I'm ok with being reminded of awesome things.

I am using impress.js for all my presentations: http://bartaz.github.io/impress.js/

I use it here and there as well. I combined it with meteor to give a presentation without having to screen share. https://github.com/phillc/meteor-impress

Example: http://phillc-cd.meteor.com/

Open in multiple tabs and click the following button in the top left and move around.

I looked at Reveal recently (the Google Chrome DevTools guys use it for all their demos) for a presentation but ended up using Bespoke.JS instead (which oddly enough the Mozilla folks have been using recently):

The following presentation gives a good overview of the differences between Bespoke and Reveal: http://markdalgleish.com/presentations/bespoke.js/

(keep pressing forward...it gets more interesting as you progress)

I liked the plugins, the docs were simple, they include grunt so your style changes are applied live, and they linked to other people presentations so you could peak at what others were doing.

In particular, I was 100% willing to switch right back to Keynote the moment any JS based presentation tool made me work on the tool more than the content. That never happened, and I ended up finishing the slides in Bespoke.
