Fullscreen presentations using twitter bootstrap and the HTML5 API

I can't take all the credit for this. I have to acknowledge the great work done by HTML5 Demos. What I did was, simplify some of the JavaScript and CSS. I then used Twitter Bootstrap as a template, so to make this work, you'll have to make that download. I also made use of the carousel library which came with Twitter Bootstrap. You'll also have to download jQuery and refer to it as I have.

Here's how it works. You load put the page in your browser. When loaded, you press the 'f' jey to make the page full screen. Press the 'enter' key to move forward through the slideshow. Press the backspace key to move back. Press the 'Esc' key when you've done.

I've tested it on Chrome and Firefox. I believe there's another popular browser, but it's not installed on my computer.

Anyway. Here's the code.
