Looks cool. I've used something similar called vroom[1] once, and it worked quite well. But as soon as I realised I want to show a live webpage (or an image), I had to switch to a browser, and then it was easier to just switch to a markdown to html presentation tool instead (I picked remark[2] which I would recommend).

That said, I think it's important to focus on the core points of the presentation and not get distracted by graphics and layouts. It makes your presentations way better.
