Fathom.js - Present JavaScript in its native environment.
If you're making a presentation on JavaScript, make it in JavaScript.
Example HTML:
<div id="presentation">
<div class="slide"> <h1>My Presentation</h1> </div>
<div class="slide"> <h2>My Dot Points</h2> <ul> <li>First dot point</li> <li>Second dot point</li> <li>Third dot point</li> </ul> </div>
</div>
jQuery Plugin Setup: $('#presentation').fathom();
Advanced Setup: var fathom = new Fathom('#presentation');
Full guide available at the official Fathom.js project page.
I've included a sample CSS file in the repo to get you started.
Please note that Fathom.js is not trying to recreate Powerpoint or Keynote. While they're good tools, I personally find that style of interface to be inappropriate on the web. If you're wondering why feature x from Powerpoint is missing, this is probably why.
If you want to contribute in a way that changes the API, please file an issue before submitting a pull request so we can dicuss how to appropriately integrate your ideas.
