I have always hated making slide decks. I find them hard to make simple-enough to be readable/elegant, yet detailed-enough to be informative. After years of fiddling with unsatisfying designs, I settled on a split-slide format I was happy with and re-used for a couple of years. I eventually got tired of it.
Recently, I started using a ReactJS+ObservableHQ+Docusaurus workflow to make interactive presentations which are (relatively) easy to maintain and deploy. In the spirit of open-source science, this page lists these presentations as-well as a post on some tips and tricks to getting started.
