presentations for busy messy hackers

branch: gh-pages

This is a ridiculous presentation system that works great for creative, hurried people. See the demo for an example of it working.

It makes text and images as big as they can be, gives you minimal styling (em), and gives you left/right arrows for navigation.


You can skip every step by doing


This is a bundle of all JS, CSS, and HTML code - which means that it's a bit harder to update, but there are no external dependencies here, so no conference-wifi-pwn.


big makes sense if you're very comfortable in JavaScript, CSS, and HTML. If you are very familiar with those languages, you can jump right in. Otherwise, here are some tips:

  • When you are working locally you can view your slides by opening your presentation in a browser. Remember to save the file as a .html.
  • Use <div> & </div> around each slide
  • You may be used to em displaying as italicized text, but in big emphasized text is green and unitalicized. You can change this default behavior in the header. (Look, Ma-- CSS in action!)
  • Paragraph tags aren't displayed in big. This can be a useful place for you to store your speaking notes. (I don't actually understand this, but I've seen it done)
  • If you'll have internet access when you present, you can reference images hosted online. If you won't, any images you want to reference will need to be in the same folder as your presentation.

Open Source


Big is totally HTML5! It uses the HTML5 doctype: <!DOCTYPE html>! It's therefore imbued with standardslicious hypeclouds.


The source looks like:

<!DOCTYPE html><html><head><title></title><link href='big.css' rel='stylesheet' type='text/css' /><script src='big.js'></script></head><body>
<div><em>Presentation software</em> for busy busy hackers</div>
<div>as <em>big</em> as it can be</div>
<div>no config</div>
<div><em>images too</em></div>
<div><img src='' /></div>
<div>JS+CSS <a href=''> tmcw/ big</a></div>


  • If you put an image as the first thing in a slide, it'll become a tiled background. I abused this power in my presentation on project it yourself
  • You can swipe left & right on mobile devices to go back and forth.

If you put something like time-to-next="5" as an attribute in a slide, the slide will pass after 5 seconds - useful for ignite talks.
