Looks nice. Related, if you already have Pandoc installed, you can get single markdown file => slideshow with Reveal.js (which the showcased site is based on) for free with

  pandoc -s -t revealjs slides.md -o slides.html

You can choose other implementations too, like good old Slidy:

  pandoc -s -t slidy slides.md -o slides.html
