A horizontal scrolling navigation pattern for touch and mouse with moving current indicator

Would you like to create a Simple Navigation with a Horizontal Subnav? It looks very similar to the Menu of Behance Network, which looks nice and professional.
We can achieve this effect purely with CSS, but since we have to attend to our red headed step child aka IE6, we will use a few lines of jQuery to cover all grounds. Nice and simple! I am sure this will come in handy in your future projects.
