Small interactive web-based presentation I made for a seminar in Learning Systems class at Halmstad University. The presentation is based on cp's deck.js maths template, described below.
I also used Google Charts Tools and Bret Victor's Tangle library for a demo, that illustrates how simple PID controller works.
A template to create slides with deck.js, MathJax, and the unicode Computer Modern fonts.
This contains everything you need to create a slideshow presentation which runs in the browser but uses the Beamer fonts and supports LaTeX maths.
deck.js is the best tool I've found to make HTML presentations.
I recompiled the cm-unicode project's Unicode version of the Computer Modern fonts (the default fonts used by LaTeX) so they could be used on the web. They can be downloaded from http://checkmyworking.com/cm-web-fonts/.
MathJax does the maths rendering.
