reveal.js - HTML Presentations
A few of my coworkers have recently shown me reveal.js, and it's quite amazing. If you have to make a presentation, the first thing everyone thinks is PowerPoint. But if we're working in the web why don't we make presentations on the web? That's where reveal.js comes in, and every time I see a presentation using reveal there's at least one or two people who ask what was used to make it.
Keeping it in the browser allows you to have live demos easily within the presentation, and by presenting you're probably already hosting your presentation for later viewing. The GitHub repository is available for forking or viewing, and what's even more amazing is there's an online editor complete with theming available!
Very cool.
