The SenatsDT implemented with the package InteractiveSlides.jl, which can be found here. For a quick setup, simply clone the repository, start a Julia session within the folder, activate and instantiate the project, and type include("startapp.jl"). This will eventually open a browser window with the demo slideshow.
Note: If InteractiveSlides.jl isn't registered yet as a package, you can also type dev https://github.com/GlobalClimateForum/InteractiveSlides.jl in order to install the package (this also allows you to edit it).
