title: Do you know any examples of a PAC design pattern?
body: <p>Can anyone point to any websites or web applications that are using the <a href="http://www.dossier-andreas.net/software_architecture/pac.html" rel="noreferrer">Presentation-Abstraction-Control</a> design pattern rather than MVC? Desktop applications are easy to find like this (e.g.; GIMP) but I'm looking for something on the web.</p>
