What is that header transition called? Where the title fades away... I like it and would like to use it.

Heyo piratebroadcas - author here. Its custom and you can view how its partly done here: http://www.roycehaynes.com/theme/js/app.js

Feel free to tweet my post! ;)

It was a little weird for me on clicking the back button. I wasn't at the top, and the transition happened in the middle of the page.
