How was this amazing drupal performance presentation ( http://rupl.github.com/high-performance-theming ) was done? Which jQ libraries are needed? And what is the best place to ask?
It's nothing overly complicated; the 3d navigation makes use of the reveal.js library.
reveal.js is a framework for easily creating beautiful presentations using HTML.
And then there are a few helper libraries:
Highlight.js- for syntax highlighting
classList.js- adds element.classList support to browsers that don't support it
carousel.js- seems to be custom DOM helper functions.
Reveal is pretty easy to use, it just requires a lot of patience and a will to succeed. Good luck!
