I really like the idea of markdown for slides,
since it keeps it simple for text-based slide
However, it has the key problem that if your slides are high in
figures, graphics, and colors then it is not going to be simple.
And to my mind the best kind of slides are not text-based,
but are full of figures.
Take a look at the first 3 slides here
(As should be obvious, I do really like Tikz)
To me they are nearly the idea slides.
- Highly visual,
- explaining the relationships in ways that are hard to convey with just speaking
- show key points that will be expanded upon in the speaking
Though they might be too full and so hard to read on a low-res/small screen
Ideally all slides would be like that, but they take a lot longer to make than just text slides.
On tools and tech for presentations
That linked latex actually contains an chunk of code,
to create a non-beamer based latex presentation.
Its key idea, (which I would like to explore more).
is that slides don’t have to fit on one screen.
The single-screen / forwards and backwards only constraint comes from the technological limitations of transparency and 35 mm slide projectors
But with how computer projectors work now,
there is no limitation to prevent you from scrolling down a slide, (leaving earlier information still visible above)
or zooming in on fine detail as you discuss a particular point.
Although zooming means you need a mouse and keyboard, so harder to do while standing.
And this also knocks out the idea of partial slide changes (e.g unveiling dot points on at a time)
Reveal.js has a related idea that slides can go forwards, backwards, up and down.
