You can find the slides here : Backbone.Marionette teaser
They were mostly a test of the extensions we are making to Deck.js for JavaScriptU. Writing modular slides in a flavor of markdown and combining them on the fly is proving to be pretty cool.
We also made a small addon for codemirror that allows for async loading of remote source and simple highlighting of test via HTML markup/markdown, two things which drove me nuts when trying to make slides before. Having to escape your code for HTML is a pain in the ass.
