Here is some useful stuff to help prepare your next awesome Python talk.

• http://slides.html5rocks.com/ - slides using latest HTML5 technologies

Not in Python, but a good stuff anyway:

• http://bartaz.github.com/impress.js - Prezi clone in CSS3

• https://github.com/schacon/showoff

• https://github.com/imakewebthings/deck.js

• http://lab.hakim.se/reveal-js/ (it looks like https://github.com/ipython/nbconvert is able to convert IPython notebooks into this format)

Generators in Python from text formats:

• https://github.com/adamzap/landslide - converts markdown, ReST, or textile to Google's html5slides template
