Today's #FreeSoftwareAdvent is reveal.js, my tool of choice for writing presentations.
I write the content in Markdown, and... that's it. Thanks to CSS, tada, I have a perfectly-formatted, ready-to-go, presentation.
It has speaker view, allows for easy PDF exports, and, because it is html, css, and JavaScript, there is no vendor lock-in *and* you can upload the presentation to your website, so that people can click/swipe through it.
I have used reveal.js for a few years now, and I absolutely love it. I can't imagine faffing around with slides these days.
