title: Full Screen Hover Signup Box -- as seen on squarespace
body: <p>I love how <a href="http://www.squarespace.com/templates/?q=minsk" rel="nofollow">http://www.squarespace.com/templates/?q=minsk</a> does their signup process -- When you click on "start with this template", the entirety of the viewport is taken over, and the signup box shows up.</p>
  
  <p>Does anyone know of a script that already does something similar to this?</p>
