Someone reminded me about reveal.js and I just took a look at the project site. It seems like reveal.js got a completely new website and a major update to version 4. I already used reveal.js for a few slides and liked it. However I didn’t consider it for my recent university presentations, because there I needed a PDF version of my slides (and the PDF export somehow didn’t work quite well with my past slides) and I didn’t really had the time to experiment. Next time I will try reveal.js again.
