Header changes as you scroll down (jQuery)
<p>TechCrunch recently redesigned their site and they have a sweet header that minifies into a thinner version of their branding as you scroll down.</p>

<p>You can see what I mean here: <a href="http://techcrunch.com/">http://techcrunch.com/</a></p>

<p>How would I go about creating something like this? Is there a tutorial anywhere and if not, can one you kind souls give me some tips on where to start? :)</p>
