There are a few GitHub repositories on my account where you can find some of my presentations, created with reveal.js, a framework for creating presentations using HTML and Markdown. - Source: dev.to / almost 4 years ago

I did not come about trying it out yet but Reveal.js looks very interesting to me and I think I will use it once I find the time to learn it... Source: 6 months ago

I think I'm not in the same ballpark but I really really liked reveal.js. Source: 8 months ago

It's reveal.js for those unfamiliar https://revealjs.com/. - Source: Hacker News / 9 months ago

I've not tried it myself or seen an example, but given the structure, it would seem like Reveal.js might give you the the sort of functionality you're looking for while having many other affordances one might look for in a digital and/or online zettelkasten. Source: 10 months ago

Right now, I'm using OpenLP , which practically does all I need (play videos, photos, and audio onto a big screen), my only issue is there is about a half second of delay between pressing on a clip and it playing, as well as no ability to cross dissolve between clips. Obviously not the biggest problem, but for a better flowing show, I would prefer something that does both of these. (Preferably free as well). Source: almost 2 years ago

I haven't used it much but OpenLP might be something to check too. It's free and open source. Https://openlp.org/. Source: over 2 years ago
