Tweak HTML5/CCS3 presentation to be more efficient.

From Brian:

Here's the site running the reveal.js presentation with the JBoss community styling:

Here's the github repo for the above site:

There are three images I used for this, a horizontally repeating top-banner, bottom banner, and the text in the bottom right. What would be useful would be new versions of these resources that repeat more gracefully, and are also smaller in width (since they repeat anyway). Having smaller images would decrease the page load time.
