I’ve just given a talk at Newcastle’s maths & stats Postgraduate Forum about zero-knowledge protocols. I don’t know very much about them but it’s an interesting topic and something fairly accessible to an audience of non-pure mathematicians.
I used deck.js, along with the Computer Modern web fonts and MathJax, to make the slides. I think it looks pretty nice! I’ve also uploaded my template deck, in case you want to build on it for your own presentations. It’s a bit big because it contains all the files needed to display the Computer Modern fonts on any browser.
